2026-08-11f2fs: support dynamic reserve/release for device aliasingDaeho Jeong
This patch adds a dynamic management feature to the existing device aliasing functionality. It allows users to dynamically reserve or release specific devices from the filesystem's free pool at runtime through new ioctls. To support this, three new ioctls are introduced: - F2FS_IOC_RESERVE_DEV_ALIAS: This reclaims the space occupied by a device aliasing file. It first performs a capacity check, resets GC victim information for the target range, marks the segments as in-use to prevent new allocations, and then triggers GC to migrate existing valid data out of the range. Finally, it reserves these blocks in the SIT to effectively exclude the device from the usable capacity. - F2FS_IOC_RELEASE_DEV_ALIAS: This releases the reserved space of a previously reserved device aliasing file. It truncates the blocks associated with the file, which makes them available for general filesystem allocation again. - F2FS_IOC_GET_DEV_ALIAS_STATUS: This retrieves the current aliasing status of a device aliasing file, returning whether the file is released (inactive alias) or reserved (active alias, with blocks fully allocated on the device).

2026-08-10ftrace: deprecate disabling via ftrace_enabled sysctlAndrey Grodzovsky
Writing 0 to kernel.ftrace_enabled has not reliably disabled ftrace for years (FTRACE_OPS_FL_PERMANENT users already block it, and more callers rely on ftrace always being on). Refuse the write instead of leaving it in an inconsistent "disables some, not all" state: return -EOPNOTSUPP and log a message. Reads and enabling (writing 1) are unaffected. Update the docs to note the deprecation up front.

2026-08-10docs: cgroup-v2: fix stale "io" controller introductionZhe Liu
The introductory paragraph for the IO controller still states that weight based distribution is "available only if cfq-iosched is in use" and that "neither scheme is available for blk-mq devices". This text dates from when the cgroup v2 documentation was first written (2015) and was correct at the time, but is no longer accurate: * cfq-iosched was removed in v5.0; * blk-mq is now the only block I/O path, and both the absolute limit scheme (io.max via blk-throttle) and the weight based scheme (io.weight via iocost, or io.bfq.weight under BFQ) work on it; * latency based protection (iolatency) and I/O priority (ioprio) controllers have since been added. The rest of the section already documents io.weight, io.max, io.cost.{qos,model}, io.latency and io.prio.class correctly, so the introduction is the only part that contradicts them. Rewrite it to reflect the current state. Signed-off-by: Zhe Liu <liuzhe1@kylinos.cn> Reviewed-by: Tao Cui <cuitao@kylinos.cn> Signed-off-by: Tejun Heo <tj@kernel.org>

The write cases of debugfs entries are provisioning and bench helpers. By designs the MPQ8646 powers the CPU core rail, so a wrong write can brown out the board or persist a bad setpoint into finite-cycle NVM. Said differently: some wrong register writes can and likely will physically damage or destroy the chip and/or the board.

2026-08-10hwmon: (pmbus) Add MPQ8646 driverVincent Jardin
Add a new driver for the MPS MPQ8646 that is a PMBus device. Beyond basic PMBus telemetry, the driver adds: - alarm acknowledge via inX_reset_history. - STATUS_WORD MPS-extended bit decode and the NVM-backed PROTECTION_LAST post-mortem, exposed as a read-only debugfs decoder. - In-driver alarm-poll fallback work item (thanks lm90) for boards without SMBALERT Signed-off-by: Vincent Jardin <vjardin@free.fr> Link: https://lore.kernel.org/r/20260730-mpq8646_v0-v7-3-e7c7ad768d5d@free.fr Signed-off-by: Guenter Roeck <linux@roeck-us.net>

The MPS MPQ8646 PMBus step-down converter uses the same mps,vout-fb-divider-ratio-permille property with the same constraints (maximum 2047, default 706) as the mps,mpq8785, so add its compatible to the existing schema.

2026-08-10dt-bindings: hwmon: (pmbus/max20830): add VOUT feedback resistor properties ↵Alexis Czezar Torreno
and complete examples Add adi,vout-rfb1-ohms and adi,vout-rfb2-ohms properties to support external voltage divider configuration for VOUT sensing. When the desired output voltage is higher than VREF, a resistor divider (RFB1 and RFB2) is required to reach the intended value. The properties use a dependency constraint to ensure both resistors are specified together, or neither. This prevents misconfiguration where only one resistor value is provided. This patch also adds missing entries in the examples.

Volterra VT7505 Add a PMBus driver for the Analog Devices MAX16545 and MAX16550, and the Volterra VT7505 controllers. The driver reports input/output voltage, input/output current, input power and temperature over PMBus. All values use the direct data format. Peak input voltage, output voltage, output current, input power and temperature readings are exposed and can be reset. The reported current and power depend on the external current-report resistor connected to the ILOAD pin, which can be provided through the "adi,rload-ohms" device tree property. On the MAX16550 and VT7505, the severe-OCP deglitch time can optionally be configured with the "adi,ocp-severe-filter-us" device tree property. When omitted, the existing hardware setting is left unchanged.

The SHT30, SHT31, SHT35 and SHT85 measure humidity and temperature and differ only in accuracy and packaging, while the STS30, STS31, STS32 and STS35 are temperature-only parts. Within each group the parts share the same software interface, so model them with a fallback to the base part of their group: "sensirion,sht30" for the SHT parts and "sensirion,sts30" for the STS parts.
