Pull erofs updates from Gao Xiang:
"In this cycle, inode page cache sharing among filesystems on the same
machine is now supported, which is particularly useful for
high-density hosts running tens of thousands of containers.
In addition, we fully isolate the EROFS core on-disk format from other
optional encoded layouts since the core on-disk part is designed to be
simple, effective, and secure. Users can use the core format to build
unique golden immutable images and import their filesystem trees
directly from raw block devices via DMA, page-mapped DAX devices,
and/or file-backed mounts without having to worry about unnecessary
intrinsic consistency issues found in other generic filesystems by
design. However, the full vision is still working in progress and will
spend more time to achieve final goals.
There are other improvements and bug fixes as usual, as listed below:
- Support inode page cache sharing among filesystems
- Formally separate optional encoded (aka compressed) inode layouts
(and the implementations) from the EROFS core on-disk aligned plain
format for future zero-trust security usage
- Improve performance by caching the fact that an inode does not have
a POSIX ACL
- Improve LZ4 decompression error reporting
- Enable LZMA by default and promote DEFLATE and Zstandard algorithms
out of EXPERIMENTAL status
- Switch to inode_set_cached_link() to cache symlink lengths
- random bugfixes and minor cleanups"

Pull misc vfs updates from Christian Brauner:
"This contains a mix of VFS cleanups, performance improvements, API
fixes, documentation, and a deprecation notice.
Scalability and performance:
- Rework pid allocation to only take pidmap_lock once instead of
twice during alloc_pid(), improving thread creation/teardown
throughput by 10-16% depending on false-sharing luck. Pad the
namespace refcount to reduce false-sharing
- Track file lock presence via a flag in ->i_opflags instead of
reading ->i_flctx, avoiding false-sharing with ->i_readcount on
open/close hot paths. Measured 4-16% improvement on 24-core
open-in-a-loop benchmarks
- Use a consume fence in locks_inode_context() to match the
store-release/load-consume idiom, eliminating a hardware fence on
some architectures
- Annotate cdev_lock with __cacheline_aligned_in_smp to prevent
false-sharing
- Remove a redundant DCACHE_MANAGED_DENTRY check in
__follow_mount_rcu() that never fires since the caller already
verifies it, eliminating a 100% mispredicted branch
- Fix a 100% mispredicted likely() in devcgroup_inode_permission()
that became wrong after a prior code reorder
Bug fixes and correctness:
- Make insert_inode_locked() wait for inode destruction instead of
skipping, fixing a corner case where two matching inodes could
exist in the hash
- Move f_mode initialization before file_ref_init() in alloc_file()
to respect the SLAB_TYPESAFE_BY_RCU ordering contract
- Add a WARN_ON_ONCE guard in try_to_free_buffers() for folios with
no buffers attached, preventing a null pointer dereference when
AS_RELEASE_ALWAYS is set but no release_folio op exists
- Fix select restart_block to store end_time as timespec64, avoiding
truncation of tv_sec on 32-bit architectures
- Make dump_inode() use get_kernel_nofault() to safely access inode
and superblock fields, matching the dump_mapping() pattern
API modernization:
- Make posix_acl_to_xattr() allocate the buffer internally since
every single caller was doing it anyway. Reduces boilerplate and
unnecessary error checking across ~15 filesystems
- Replace deprecated simple_strtoul() with kstrtoul() for the
ihash_entries, dhash_entries, mhash_entries, and mphash_entries
boot parameters, adding proper error handling
- Convert chardev code to use guard(mutex) and __free(kfree) cleanup
patterns
- Replace min_t() with min() or umin() in VFS code to avoid silently
truncating unsigned long to unsigned int
- Gate LOOKUP_RCU assertions behind CONFIG_DEBUG_VFS since callers
already check the flag
Deprecation:
- Begin deprecating legacy BSD process accounting (acct(2)). The
interface has numerous footguns and better alternatives exist
(eBPF)
Documentation:
- Fix and complete kernel-doc for struct export_operations, removing
duplicated documentation between ReST and source
- Fix kernel-doc warnings for __start_dirop() and ilookup5_nowait()
Testing:
- Add a kunit test for initramfs cpio handling of entries with
filesize > PATH_MAX
Misc:
- Add missing <linux/init_task.h> include in fs_struct.c"

Pull vfs mount updates from Christian Brauner:
- statmount: accept fd as a parameter
Extend struct mnt_id_req with a file descriptor field and a new
STATMOUNT_BY_FD flag. When set, statmount() returns mount information
for the mount the fd resides on — including detached mounts
(unmounted via umount2(MNT_DETACH)).
For detached mounts the STATMOUNT_MNT_POINT and STATMOUNT_MNT_NS_ID
mask bits are cleared since neither is meaningful. The capability
check is skipped for STATMOUNT_BY_FD since holding an fd already
implies prior access to the mount and equivalent information is
available through fstatfs() and /proc/pid/mountinfo without
privilege. Includes comprehensive selftests covering both attached
and detached mount cases.
- fs: Remove internal old mount API code (1 patch)
Now that every in-tree filesystem has been converted to the new
mount API, remove all the legacy shim code in fs_context.c that
handled unconverted filesystems. This deletes ~280 lines including
legacy_init_fs_context(), the legacy_fs_context struct, and
associated wrappers. The mount(2) syscall path for userspace remains
untouched. Documentation references to the legacy callbacks are
cleaned up.
- mount: add OPEN_TREE_NAMESPACE to open_tree()
Container runtimes currently use CLONE_NEWNS to copy the caller's
entire mount namespace — only to then pivot_root() and recursively
unmount everything they just copied. With large mount tables and
thousands of parallel container launches this creates significant
contention on the namespace semaphore.
OPEN_TREE_NAMESPACE copies only the specified mount tree (like
OPEN_TREE_CLONE) but returns a mount namespace fd instead of a
detached mount fd. The new namespace contains the copied tree mounted
on top of a clone of the real rootfs.
This functions as a combined unshare(CLONE_NEWNS) + pivot_root() in a
single syscall. Works with user namespaces: an unshare(CLONE_NEWUSER)
followed by OPEN_TREE_NAMESPACE creates a mount namespace owned by
the new user namespace. Mount namespace file mounts are excluded from
the copy to prevent cycles. Includes ~1000 lines of selftests"

Pull vfs nullfs update from Christian Brauner:
"Add a completely catatonic minimal pseudo filesystem called "nullfs"
and make pivot_root() work in the initramfs.
Currently pivot_root() does not work on the real rootfs because it
cannot be unmounted. Userspace has to recursively delete initramfs
contents manually before continuing boot, using the fragile
switch_root sequence (overmount + chroot).
Add nullfs, a minimal immutable filesystem that serves as the true
root of the mount hierarchy. The mutable rootfs (tmpfs/ramfs) is
mounted on top of it. This allows userspace to simply:
chdir(new_root);
pivot_root(".", ".");
umount2(".", MNT_DETACH);
without the traditional switch_root workarounds. systemd already
handles this correctly. It tries pivot_root() first and falls back
to MS_MOVE only when that fails.
This also means rootfs mounts in unprivileged namespaces no longer
need MNT_LOCKED, since the immutable nullfs guarantees nothing can be
revealed by unmounting the covering mount.
nullfs is a single-instance filesystem (get_tree_single()) marked
SB_NOUSER | SB_I_NOEXEC | SB_I_NODEV with an immutable empty root
directory. This means sooner or later it can be used to overmount
other directories to hide their contents without any additional
protection needed.
We enable it unconditionally. If we see any real regression we'll
hide it behind a boot option.
nullfs has extensions beyond this in the future. It will serve as a
concept to support the creation of completely empty mount namespaces -
which is work coming up in the next cycle"

Pull vfs lease updates from Christian Brauner:
"This contains updates for lease support to require filesystems to
explicitly opt-in to lease support
Currently kernel_setlease() falls through to generic_setlease() when a
a filesystem does not define ->setlease(), silently granting lease
support to every filesystem regardless of whether it is prepared for
it.
This is a poor default: most filesystems never intended to support
leases, and the silent fallthrough makes it impossible to distinguish
"supports leases" from "never thought about it".
This inverts the default. It adds explicit
.setlease = generic_setlease;
assignments to every in-tree filesystem that should retain lease
support, then changes kernel_setlease() to return -EINVAL when
->setlease is NULL.
With the new default in place, simple_nosetlease() is redundant and
is removed along with all references to it"

Pull vfs timestamp updates from Christian Brauner:
"This contains the changes to support non-blocking timestamp updates.
Since commit 66fa3cedf16a ("fs: Add async write file modification
handling") file_update_time_flags() unconditionally returns -EAGAIN
when any timestamp needs updating and IOCB_NOWAIT is set. This makes
non-blocking direct writes impossible on file systems with granular
enough timestamps, which in practice means all of them.
This reworks the timestamp update path to propagate IOCB_NOWAIT
through ->update_time so that file systems which can update timestamps
without blocking are no longer penalized.
With that groundwork in place, the core change passes IOCB_NOWAIT into
->update_time and returns -EAGAIN only when the file system indicates
it would block.
XFS implements non-blocking timestamp updates by using the new
->sync_lazytime and open-coding generic_update_time without the
S_NOWAIT check, since the lazytime path through the generic helpers
can never block in XFS"

Pull vfs initrd removal from Christian Brauner:
"Remove the deprecated linuxrc-based initrd code path and related dead
code. The linuxrc initrd path was deprecated in 2020 and this series
completes its removal. If we see real-life regressions we'll revert.
The core change removes handle_initrd() and init_linuxrc() — the
entire flow that ran /linuxrc from an initrd, pivoted roots, and
handed off to the real root filesystem. With that gone, initrd_load()
becomes void (no longer short-circuits prepare_namespace()),
rd_load_image() is simplified to always load /initrd.image instead of
taking a path, and rd_load_disk() is deleted.
The /proc/sys/kernel/real-root-dev sysctl and its backing variable are
removed since they only existed for linuxrc to communicate the real
root device back to the kernel.
The no-op load_ramdisk= and prompt_ramdisk= parameters are dropped,
and noinitrd and ramdisk_start= gain deprecation warnings.
Initramfs is entirely unaffected. The non-linuxrc initrd path
(root=/dev/ram0) is preserved but now carries a deprecation warning

KVM x86 misc changes for 6.20
- Disallow changing the virtual CPU model if L2 is active, for all the same
reasons KVM disallows change the model after the first KVM_RUN.
- Fix a bug where KVM would incorrectly reject host accesses to PV MSRs that
were advertised as supported to userspace when running with
KVM_CAP_ENFORCE_PV_FEATURE_CPUID enabled.
- Fix a bug where KVM would attempt to read protect guest state (CR3) when
configuring an async #PF entry.
- Fail the build if EXPORT_SYMBOL_GPL or EXPORT_SYMBOL is used in KVM (for x86
only) to enforce usage of EXPORT_SYMBOL_FOR_KVM_INTERNAL. Explicitly allow
the few exports that are intended for external usage.
- Ignore -EBUSY when checking nested events after a vCPU exits blocking as
the WARN is user-triggerable, and because exiting to userspace on -EBUSY
does more harm than good in pretty much every situation.
- Throw in the towel and drop the WARN on INIT/SIPI being blocked when vCPU is
in Wait-For-SIPI, as playing whack-a-mole with syzkaller turned out to be an
unwinnable game.
- Add support for new Intel instructions that don't require anything beyond
enumerating feature flags to userspace.
- Grab SRCU when reading PDPTRs in KVM_GET_SREGS2.
- Add WARNs to guard against modifying KVM's CPU caps outside of the intended
setup flow, as nested VMX in particular is sensitive to unexpected changes
in KVM's golden configuration.
- Add a quirk to allow userspace to opt-in to actually suppress EOI broadcasts
when the suppression feature is enabled by the guest (currently limited to
split IRQCHIP, i.e. userspace I/O APIC). Sadly, simply fixing KVM to honor
Suppress EOI Broadcasts isn't an option as some userspaces have come to rely
on KVM's buggy behavior (KVM advertises Supress EOI Broadcast irrespective
of whether or not userspace I/O APIC supports Directed EOIs).
- Minor cleanups.

KVM SVM changes for 6.20
- Drop a user-triggerable WARN on nested_svm_load_cr3() failure.
- Add support for virtualizing ERAPS. Note, correct virtualization of ERAPS
relies on an upcoming, publicly announced change in the APM to reduce the
set of conditions where hardware (i.e. KVM) *must* flush the RAP.
- Ignore nSVM intercepts for instructions that are not supported according to
L1's virtual CPU model.
- Add support for expedited writes to the fast MMIO bus, a la VMX's fastpath
for EPT Misconfig.
- Don't set GIF when clearing EFER.SVME, as GIF exists independently of SVM,
and allow userspace to restore nested state with GIF=0.
- Treat exit_code as an unsigned 64-bit value through all of KVM.
- Add support for fetching SNP certificates from userspace.
- Fix a bug where KVM would use vmcb02 instead of vmcb01 when emulating VMLOAD
or VMSAVE on behalf of L2.
- Misc fixes and cleanups.

ASoC: Updates for v7.0
This release is almost all abut driers, there's very little core work
here, although some of that driver work is in more generic areas like
SDCA and SOF:
- Generic SDCA support for reporting jack events.
- Continuing platform support, cleanup and feature improements for the
AMD, Intel, Qualcomm and SOF code.
- Platform description improvements for the Cirrus drivers.
- Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
CV1800B.
We also pulled in one small SPI API update and some more substantial
regmap work (cache description improvements) for use in drivers.

- support for new firmware handling in intel-ish-hid (Vishnu Sankar)

Introduce a mechanism for managing global kernel state whose lifecycle is
tied to the preservation of one or more files. This is necessary for
subsystems where multiple preserved file descriptors depend on a single,
shared underlying resource.
An example is HugeTLB, where multiple file descriptors such as memfd and
guest_memfd may rely on the state of a single HugeTLB subsystem.
Preserving this state for each individual file would be redundant and
incorrect. The state should be preserved only once when the first file is
preserved, and restored/finished only once the last file is handled.
This patch introduces File-Lifecycle-Bound (FLB) objects to solve this
problem. An FLB is a global, reference-counted object with a defined set
of operations:
- A file handler (struct liveupdate_file_handler) declares a dependency
on one or more FLBs via a new registration function,
liveupdate_register_flb().
- When the first file depending on an FLB is preserved, the FLB's
.preserve() callback is invoked to save the shared global state. The
reference count is then incremented for each subsequent file.
- Conversely, when the last file is unpreserved (before reboot) or
finished (after reboot), the FLB's .unpreserve() or .finish() callback
is invoked to clean up the global resource.
The implementation includes:
- A new set of ABI definitions (luo_flb_ser, luo_flb_head_ser) and a
corresponding FDT node (luo-flb) to serialize the state of all active
FLBs and pass them via Kexec Handover.
- Core logic in luo_flb.c to manage FLB registration, reference
counting, and the invocation of lifecycle callbacks.
- An API (liveupdate_flb_get/_incoming/_outgoing) for other kernel
subsystems to safely access the live object managed by an FLB, both
before and after the live update.
This framework provides the necessary infrastructure for more complex
subsystems like IOMMU, VFIO, and KVM to integrate with the Live Update
Orchestrator.

Patch series "list private v2 & luo flb", v9.
This series introduces two connected infrastructure improvements: a new
API for handling private linked lists, and the "File-Lifecycle-Bound"
(FLB) mechanism for the Live Update Orchestrator.
1. Private List Primitives (patches 1-3)
Recently, Linux introduced the ability to mark structure members as
__private and access them via ACCESS_PRIVATE(). This enforces better
encapsulation by ensuring internal details are only accessible by the
owning subsystem.
However, struct list_head is frequently used as an internal linkage
mechanism within these private sections. The standard macros in
<linux/list.h> do not support ACCESS_PRIVATE() natively. Consequently,
subsystems using private lists are forced to implement ad-hoc
workarounds or local iterator macros.
This series adds <linux/list_private.h>, providing a set of
primitives identical to those in <linux/list.h> but designed for
private list heads. It also includes a KUnit test suite to verify that
the macros correctly handle pointer offsets and qualifiers.
2. This series adds FLB (patches 4-5) support to Live Update that also
internally uses private lists.
FLB allows global kernel state (such as IOMMU domains or HugeTLB
state) to be preserved once, shared across multiple file descriptors,
and restored when needed. This is necessary for subsystems where
multiple preserved file descriptors depend on a single, shared
underlying resource. Preserving this state for each individual file
would be redundant and incorrect.
FLB uses reference counting tied to the lifecycle of preserved
files. The state is preserved when the first file depending on it is
preserved, and restored or cleaned up only when the last file is
handled.
This patch (of 5):
Linux recently added an ability to add private members to structs (i.e.
__private) and access them via ACCESS_PRIVATE(). This ensures that those
members are only accessible by the subsystem which owns the struct type,
and not to the object owner.
However, struct list_head often needs to be placed into the private
section to be manipulated privately by the subsystem.
Add macros to support private list manipulations in
<linux/list_private.h>.

Add a new module parameter 'panic_on_stall_time' that triggers a panic
when a workqueue stall persists for longer than the specified duration
in seconds.
Unlike 'panic_on_stall' which counts accumulated stall events, this
parameter triggers based on the duration of a single continuous stall.
This is useful for catching truly stuck workqueues rather than
accumulating transient stalls.
Usage:
workqueue.panic_on_stall_time=120
This would panic if any workqueue pool has been stalled for 120 seconds
or more.
The stall duration is measured from the workqueue last progress
(poll_ts) which accounts for legitimate system stalls.

Add new compatible string 'fsl,imx952-asrc' for i.MX952 platform,
below are the differences that make this ASRC not fallback compatible
with other platforms.
1) There is a power domain on i.MX952 for the wakeupmix system where
ASRC is in. But it is enabled by default, ASRC device don't need
to enable it, so it is optional for i.MX952.
2) The clock sources of ASRC are different on i.MX952.
3) There is a limitation on i.MX952 that DMA request is not cleared at the
end of conversion with dma slave mode. Which causes sample is dropped from
the input fifo on the second time if DMA is triggered before the client
device and DMA may copy wrong data from output fifo as the output fifo is
not ready in the beginning. So there is specially handling in the driver.

uuid=off,index=on required that all upper/lower directories are on the
same filesystem.
Relax the requirement so that only all the lower directories need to be
on the same filesystem.

The boot integrity attribute represents that the CPU or APU is used for the
hardware root of trust in the boot process. This bit only represents the
CPU/APU and some vendors have other hardware root of trust implementations
specific to their designs.

Move the DRM buddy allocator one level up so that it can be used by GPU
drivers (example, nova-core) that have usecases other than DRM (such as
VFIO vGPU support). Modify the API, structures and Kconfigs to use
"gpu_buddy" terminology. Adapt the drivers and tests to use the new API.
The commit cannot be split due to bisectability, however no functional
change is intended. Verified by running K-UNIT tests and build tested
various configurations.

[airlied: I've split this into two so git can find copies easier.
I've also just nuked drm_random library, that stuff needs to be done
elsewhere and only the buddy tests seem to be using it].

Merge series from "Miquel Raynal (Schneider Electric)" <miquel.raynal@bootlin.com>:
This series adds support for the QSPI controller available on Renesas
RZ/N1S and RZ/N1D SoC. It has been tested with a custom board (see last
SPI patch for details), but has been tested by Wolfram (thank you!) on
the DB board.
Link: https://lore.kernel.org/linux-devicetree/20260116114852.52948-2-wsa+renesas@sang-engineering.com/
Adding support for this SoC required a few adaptations to the Cadence
QSPI driver which have already been merged (except one regarding clocks
handling). This series contains the remaining patches, the ones actually
adding support for the RZ/N1 flavour.

Move enable/disable GuC RC logic into the new file. This will
allow us to independently enable/disable GuC RC and not rely
on SLPC related functions. GuC already provides separate H2G
interfaces to setup GuC RC and SLPC.

Add support for the Renesas RZ/N1D400 QSPI controller.
This SoC is identified in the bindings with its other name: r9a06g032.
It is part of the RZ/N1 family, which contains a "D" and a "S"
variant. IPs in this SoC are typically described using 2 compatibles:
the SoC specific compatible and the family compatible. The original
Cadence IP compatible is dropped because it is unusable on its own.
Indirect accesses are not supported by this flavour of the Cadence IP,
which means several properties have no meaning in the scope of the
Renesas compatible. Let's make sure they are no longer expected nor
mandatory.

Document the Renesas USBHS controller found on the Renesas RZ/G3E SoC.
The USBHS block on RZ/G3E is functionally identical to the one found
on the RZ/G2L family, so no driver changes are needed. The existing
"renesas,rzg2l-usbhs" fallback compatible will continue to be used for
handling this IP.
