Sphinx's LaTeX builder fails when converting the nested ASCII tables in
f2fs.rst, producing the following error:
"Markup is unsupported in LaTeX: longtable does not support nesting a table."
Wrap the affected ASCII tables in literal code blocks to force Sphinx to
render them verbatim. This prevents nested longtables and fixes the PDF
build failure on Sphinx 8.2.x.

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Replace busylock at the Tx queuing layer with a lockless list.
Resulting in a 300% (4x) improvement on heavy TX workloads, sending
twice the number of packets per second, for half the cpu cycles.
- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue.
Normally we perform queue re-selection when flow comes out of idle,
but under extreme circumstances the flows may be constantly busy.
Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.
- Optimize the NAPI skb cache, make it larger, use it in more paths.
- Attempt returning Tx skbs to the originating CPU (like we already
did for Rx skbs).
- Various data structure layout and prefetch optimizations from Eric.
- Remove ktime_get() from the recvmsg() fast path, ktime_get() is
sadly quite expensive on recent AMD machines.
- Extend threaded NAPI polling to allow the kthread busy poll for
packets.
- Make MPTCP use Rx backlog processing. This lowers the lock
pressure, improving the Rx performance.
- Support memcg accounting of MPTCP socket memory.
- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor
fit for modern container workloads, where limits are imposed using
cgroups.
- Improve heuristics for when to kick off AF_UNIX garbage collection.
- Allow users to control TCP SACK compression, and default to 33% of
RTT.
- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid
unnecessarily aggressive rcvbuf growth and overshot when the
connection RTT is low.
- Preserve skb metadata space across skb_push / skb_pull operations.
- Support for IPIP encapsulation in the nftables flowtable offload.
- Support appending IP interface information to ICMP messages (RFC
5837).
- Support setting max record size in TLS (RFC 8449).
- Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.
- Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.
- Let users configure the number of write buffers in SMC.
- Add new struct sockaddr_unsized for sockaddr of unknown length,
from Kees.
- Some conversions away from the crypto_ahash API, from Eric Biggers.
- Some preparations for slimming down struct page.
- YAML Netlink protocol spec for WireGuard.
- Add a tool on top of YAML Netlink specs/lib for reporting commonly
computed derived statistics and summarized system state.
Driver API:
- Add CAN XL support to the CAN Netlink interface.
- Add uAPI for reporting PHY Mean Square Error (MSE) diagnostics, as
defined by the OPEN Alliance's "Advanced diagnostic features for
100BASE-T1 automotive Ethernet PHYs" specification.
- Add DPLL phase-adjust-gran pin attribute (and implement it in
zl3073x).
- Refactor xfrm_input lock to reduce contention when NIC offloads
IPsec and performs RSS.
- Add info to devlink params whether the current setting is the
default or a user override. Allow resetting back to default.
- Add standard device stats for PSP crypto offload.
- Leverage DSA frame broadcast to implement simple HSR frame
duplication for a lot of switches without dedicated HSR offload.
- Add uAPI defines for 1.6Tbps link modes.
Device drivers:
- Add Motorcomm YT921x gigabit Ethernet switch support.
- Add MUCSE driver for N500/N210 1GbE NIC series.

and away from the direct IOCTL handling. While at it support GET
operations for PHY timestamping.

git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux
Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Add support for 'syn'.
Syn is a parsing library for parsing a stream of Rust tokens into a
syntax tree of Rust source code.
Currently this library is geared toward use in Rust procedural
macros, but contains some APIs that may be useful more generally.
'syn' allows us to greatly simplify writing complex macros such as
'pin-init' (Benno has already prepared the 'syn'-based version). We
will use it in the 'macros' crate too.
'syn' is the most downloaded Rust crate (according to crates.io),
and it is also used by the Rust compiler itself. While the amount
of code is substantial, there should not be many updates needed for
these crates, and even if there are, they should not be too big,
e.g. +7k -3k lines across the 3 crates in the last year.
'syn' requires two smaller dependencies: 'quote' and 'proc-macro2'.
I only modified their code to remove a third dependency
('unicode-ident') and to add the SPDX identifiers. The code can be
easily verified to exactly match upstream with the provided
scripts.
They are all licensed under "Apache-2.0 OR MIT", like the other
vendored 'alloc' crate we had for a while.
Please see the merge commit with the cover letter for more context.
- Allow 'unreachable_pub' and 'clippy::disallowed_names' for
doctests.
Examples (i.e. doctests) may want to do things like show public
items and use names such as 'foo'.
Nevertheless, we still try to keep examples as close to real code
as possible (this is part of why running Clippy on doctests is
important for us, e.g. for safety comments, which userspace Rust
does not support yet but we are stricter).
'kernel' crate:
- Replace our custom 'CStr' type with 'core::ffi::CStr'.
Using the standard library type reduces our custom code footprint,
and we retain needed custom functionality through an extension
trait and a new 'fmt!' macro which replaces the previous 'core'
import.
This started in 6.17 and continued in 6.18, and we finally land the
replacement now. This required quite some stamina from Tamir, who
split the changes in steps to prepare for the flag day change here.
- Replace 'kernel::c_str!' with C string literals.
C string literals were added in Rust 1.77, which produce '&CStr's
(the 'core' one), so now we can write:
c"hi"
instead of:
c_str!("hi")
- Add 'num' module for numerical features.
It includes the 'Integer' trait, implemented for all primitive
integer types.
It also includes the 'Bounded' integer wrapping type: an integer
value that requires only the 'N' least significant bits of the
wrapped type to be encoded:
// An unsigned 8-bit integer, of which only the 4 LSBs are used.
let v = Bounded::<u8, 4>::new::<15>();
assert_eq!(v.get(), 15);
'Bounded' is useful to e.g. enforce guarantees when working with
bitfields that have an arbitrary number of bits.
Values can also be constructed from simple non-constant expressions
or, for more complex ones, validated at runtime.
'Bounded' also comes with comparison and arithmetic operations
(with both their backing type and other 'Bounded's with a
compatible backing type), casts to change the backing type,
extending/shrinking and infallible/fallible conversions from/to
primitives as applicable.
- 'rbtree' module: add immutable cursor ('Cursor').
It enables to use just an immutable tree reference where
appropriate. The existing fully-featured mutable cursor is renamed
to 'CursorMut'.
kallsyms:
- Fix wrong "big" kernel symbol type read from procfs.
'pin-init' crate:
- A couple minor fixes (Benno asked me to pick these patches up for
him this cycle).
Documentation:
- Quick Start guide: add Debian 13 (Trixie).
Debian Stable is now able to build Linux, since Debian 13 (released
2025-08-09) packages Rust 1.85.0, which is recent enough.
We are planning to propose that the minimum supported Rust version
in Linux follows Debian Stable releases, with Debian 13 being the
first one we upgrade to, i.e. Rust 1.85.
MAINTAINERS:
- Add entry for the new 'num' module.
- Remove Alex as Rust maintainer: he hasn't had the time to
contribute for a few years now, so it is a no-op change in
practice.
And a few other cleanups and improvements"

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- Allow creaing nbcon console drivers with an unsafe write_atomic()
callback that can only be called by the final nbcon_atomic_flush_unsafe().
Otherwise, the driver would rely on the kthread.
It is going to be used as the-best-effort approach for an
experimental nbcon netconsole driver, see
https://lore.kernel.org/r/20251121-nbcon-v1-2-503d17b2b4af@debian.org
Note that a safe .write_atomic() callback is supposed to work in NMI
context. But some networking drivers are not safe even in IRQ
context:
https://lore.kernel.org/r/oc46gdpmmlly5o44obvmoatfqo5bhpgv7pabpvb6sjuqioymcg@gjsma3ghoz35
In an ideal world, all networking drivers would be fixed first and
the atomic flush would be blocked only in NMI context. But it brings
the question how reliable networking drivers are when the system is
in a bad state. They might block flushing more reliable serial
consoles which are more suitable for serious debugging anyway.
- Allow to use the last 4 bytes of the printk ring buffer.
- Prevent queuing IRQ work and block printk kthreads when consoles are
suspended. Otherwise, they create non-necessary churn or even block
the suspend.
- Release console_lock() between each record in the kthread used for
legacy consoles on RT. It might significantly speed up the boot.
- Release nbcon context between each record in the atomic flush. It
prevents stalls of the related printk kthread after it has lost the
ownership in the middle of a record
- Add support for NBCON consoles into KDB
- Add %ptsP modifier for printing struct timespec64 and use it where
possible

git://git.kernel.org/pub/scm/linux/kernel/git/rcu/linux
Pull RCU updates from Frederic Weisbecker:
"SRCU:
- Properly handle SRCU readers within IRQ disabled sections in tiny
SRCU
- Preparation to reimplement RCU Tasks Trace on top of SRCU fast:
- Introduce API to expedite a grace period and test it through
rcutorture
- Split srcu-fast in two flavours: SRCU-fast and SRCU-fast-updown.
Both are still targeted toward faster readers (without full
barriers on LOCK and UNLOCK) at the expense of heavier write
side (using full RCU grace period ordering instead of simply
full ordering) as compared to "traditional" non-fast SRCU. But
those srcu-fast flavours are going to be optimized in two
different ways:
- SRCU-fast will become the reimplementation basis for
RCU-TASK-TRACE for consolidation. Since RCU-TASK-TRACE must
be NMI safe, SRCU-fast must be as well.
- SRCU-fast-updown will be needed for uretprobes code in order
to get rid of the read-side memory barriers while still
allowing entering the reader at task level while exiting it
in a timer handler. It is considered semaphore-like in that
it can have different owners between LOCK and UNLOCK.
However it is not NMI-safe.
The actual optimizations are work in progress for the next
cycle. Only the new interfaces are added for now, along with
related torture and scalability test code.
- Create/document/debug/torture new proper initializers for RCU fast:
DEFINE_SRCU_FAST() and init_srcu_struct_fast()
This allows for using right away the proper ordering on the write
side (either full ordering or full RCU grace period ordering)
without waiting for the read side to tell which to use.
This also optimizes the read side altogether with moving flavour
debug checks under debug config and with removing a costly RmW
operation on their first call.
- Make some diagnostic functions tracing safe
Refscale:
- Add performance testing for common context synchronizations
(Preemption, IRQ, Softirq) and per-cpu increments. Those are
relevant comparisons against SRCU-fast read side APIs, especially
as they are planned to synchronize further tracing fast-path code
Miscellanous:
- In order to prepare the layout for nohz_full work deferral to user
exit, the context tracking state must shrink the counter of
transitions to/from RCU not watching. The only possible hazard is
to trigger wrap-around more easily, delaying a bit grace periods
when that happens. This should be a rare event though. Yet add
debugging and torture code to test that assumption
- Fix memory leak on locktorture module
- Annotate accesses in rculist_nulls.h to prevent from KCSAN
warnings. On recent discussions, we also concluded that all those
WRITE_ONCE() and READ_ONCE() on list APIs deserve appropriate
comments. Something to be expected for the next cycle
- Provide a script to apply several configs to several commits with
torture
- Allow torture to reuse a build directory in order to save needless
rebuild time
- Various cleanups"

Pull documentation updates from Jonathan Corbet:
"This has been another busy cycle for documentation, with a lot of
build-system thrashing. That work should slow down from here on out.
- The various scripts and tools for documentation were spread out in
several directories; now they are (almost) all coalesced under
tools/docs/. The holdout is the kernel-doc script, which cannot be
easily moved without some further thought.
- As the amount of Python code increases, we are accumulating modules
that are imported by multiple programs. These modules have been
pulled together under tools/lib/python/ -- at least, for
documentation-related programs. There is other Python code in the
tree that might eventually want to move toward this organization.
- The Perl kernel-doc.pl script has been removed. It is no longer
used by default, and nobody has missed it, least of all anybody who
actually had to look at it.
- The docs build was controlled by a complex mess of makefilese that
few dared to touch. Mauro has moved that logic into a new program
(tools/docs/sphinx-build-wrapper) that, with any luck at all, will
be far easier to understand and maintain.
- The get_feat.pl program, used to access information under
Documentation/features/, has been rewritten in Python, bringing an
end to the use of Perl in the docs subsystem.
- The top-level README file has been reorganized into a more
reader-friendly presentation.
- A lot of Chinese translation additions
- Typo fixes and documentation updates as usual"

The x86 bootloader ID specification text uses hexadecimal
values without a 0x prefix:
D kexec-tools
E Extended (see ext_loader_type)
F Special (0xFF = undefined)
10 Reserved
11 Minimal Linux Bootloader
<http://sebastian-plotz.blogspot.de>
12 OVMF UEFI virtualization stack
13 barebox
Which beyond the ambiguity of '13' in isolation, also
made me fail a grep -wi '0xd' when I was looking for
the kexec bootloader ID definition and caused quite
a bit of head-scratching before I found out why it
didn't show up.
Furthermore, the actual explanatory text uses the 0x
prefix:
For boot loader IDs above T = 0xD, write T = 0xE to this field and
write the extended ID minus 0x10 to the ext_loader_type field.
Similarly, the ext_loader_ver field can be used to provide more than
four bits for the bootloader version.
So make it all both unambiguous, easy to grep and consistent
across the entire documentation by prefixing the IDs with 0x.

Extracting empty examples results in just the empty template being
generated and then validated. That's pointless and not free, so filter
out the schemas without any examples from the targets.
There's currently a little less than 10% of the binding schema files
without examples. Removing them improves the build time by ~6%.

Backmerging to bring in a needed dependency for the Xe VFIO
driver variant. This should ideally have been done before we
commited that, so we now have a small window in drm-xe-next

Pull crypto library test updates from Eric Biggers:
- Add KUnit test suites for SHA-3, BLAKE2b, and POLYVAL. These are the
algorithms that have new crypto library interfaces this cycle.
- Remove the crypto_shash POLYVAL tests. They're no longer needed
because POLYVAL support was removed from crypto_shash. Better POLYVAL
test coverage is now provided via the KUnit test suite.

Pull crypto library updates from Eric Biggers:
"This is the main crypto library pull request for 6.19. It includes:
- Add SHA-3 support to lib/crypto/, including support for both the
hash functions and the extendable-output functions. Reimplement the
existing SHA-3 crypto_shash support on top of the library.
This is motivated mainly by the upcoming support for the ML-DSA
signature algorithm, which needs the SHAKE128 and SHAKE256
functions. But even on its own it's a useful cleanup.
This also fixes the longstanding issue where the
architecture-optimized SHA-3 code was disabled by default.
- Add BLAKE2b support to lib/crypto/, and reimplement the existing
BLAKE2b crypto_shash support on top of the library.
This is motivated mainly by btrfs, which supports BLAKE2b
checksums. With this change, all btrfs checksum algorithms now have
library APIs. btrfs is planned to start just using the library
directly.
This refactor also improves consistency between the BLAKE2b code
and BLAKE2s code. And as usual, it also fixes the issue where the
architecture-optimized BLAKE2b code was disabled by default.
- Add POLYVAL support to lib/crypto/, replacing the existing POLYVAL
support in crypto_shash. Reimplement HCTR2 on top of the library.
This simplifies the code and improves HCTR2 performance. As usual,
it also makes the architecture-optimized code be enabled by
default. The generic implementation of POLYVAL is greatly improved
as well.
- Clean up the BLAKE2s code
- Add FIPS self-tests for SHA-1, SHA-2, and SHA-3"

Pull arm64 updates from Catalin Marinas:
"These are the arm64 updates for 6.19.
The biggest part is the Arm MPAM driver under drivers/resctrl/.
There's a patch touching mm/ to handle spurious faults for huge pmd
(similar to the pte version). The corresponding arm64 part allows us
to avoid the TLB maintenance if a (huge) page is reused after a write
fault. There's EFI refactoring to allow runtime services with
preemption enabled and the rest is the usual perf/PMU updates and
several cleanups/typos.
Summary:
Core features:
- Basic Arm MPAM (Memory system resource Partitioning And Monitoring)
driver under drivers/resctrl/ which makes use of the fs/rectrl/ API
Perf and PMU:
- Avoid cycle counter on multi-threaded CPUs
- Extend CSPMU device probing and add additional filtering support
for NVIDIA implementations
- Add support for the PMUs on the NoC S3 interconnect
- Add additional compatible strings for new Cortex and C1 CPUs
- Add support for data source filtering to the SPE driver
- Add support for i.MX8QM and "DB" PMU in the imx PMU driver
Memory managemennt:
- Avoid broadcast TLBI if page reused in write fault
- Elide TLB invalidation if the old PTE was not valid
- Drop redundant cpu_set_*_tcr_t0sz() macros
- Propagate pgtable_alloc() errors outside of __create_pgd_mapping()
- Propagate return value from __change_memory_common()
ACPI and EFI:
- Call EFI runtime services without disabling preemption
- Remove unused ACPI function
Miscellaneous:
- ptrace support to disable streaming on SME-only systems
- Improve sysreg generation to include a 'Prefix' descriptor
- Replace __ASSEMBLY__ with __ASSEMBLER__
- Align register dumps in the kselftest zt-test
- Remove some no longer used macros/functions

- Remove compat support. There shouldn't be any compat user space
around anymore, therefore get rid of a lot of code which also doesn't
need to be tested anymore
- Add stackprotector support. GCC 16 will get new compiler options,
which allow to generate code required for kernel stackprotector
support

Pull clocksource updates from Thomas Gleixner:
"Updates for clocksource and clockevent drivers:
- A new driver for the Realtel system timer
- Prevent the unbinding of timers when the drivers do not support
that
- Expand the timer counter readout for the SPRD driver to 64 bit
to allow IOT devices suspend times of more than 36 hours, which
is the current limit of the 32-bi readout
- The usual small cleanups, fixes and enhancements all over the
place"

KVM/arm64 updates for 6.19
- Support for userspace handling of synchronous external aborts (SEAs),
allowing the VMM to potentially handle the abort in a non-fatal
manner.
- Large rework of the VGIC's list register handling with the goal of
supporting more active/pending IRQs than available list registers in
hardware. In addition, the VGIC now supports EOImode==1 style
deactivations for IRQs which may occur on a separate vCPU than the
one that acked the IRQ.
- Support for FEAT_XNX (user / privileged execute permissions) and
FEAT_HAF (hardware update to the Access Flag) in the software page
table walkers and shadow MMU.
- Allow page table destruction to reschedule, fixing long need_resched
latencies observed when destroying a large VM.
- Minor fixes to KVM and selftests
