4 daysnet: add the driver-facing netdev_work scheduling APIJakub Kicinski
With an extra event mask we can easily extend the netdev work to also service driver-defined events. For advanced drivers this is probably not a perfect match, but it makes running deferred work easier in simple cases. Expose the netdev_work facility to drivers. Add helpers to schedule work and a dedicated ndo to perform the driver- -scheduled actions.

4 daysnet: turn the rx_mode work into a generic netdev_work facilityJakub Kicinski
The rx_mode update runs from a workqueue: drivers have their ndo_set_rx_mode_async() callback executed by a single global work item under RTNL and ops lock. This is a useful pattern. Support multiple "events" that need to be serviced and make RX_MODE sync the first one. Call the events "core" because later on we will let drivers define and schedule their own.

5 daysblock: fix GFP_ flags confusion in bio_integrity_alloc_bufChristoph Hellwig
bio_integrity_alloc_buf usage of GFP_ flags is messed up. For one it mixes GFP_NOFS and GFP_NOIO for neighbouring allocations, but it also makes the allocations fail more often than needed. That code was copied from bio_alloc_bioset which needs to do that so that it can punt to the rescuer workqueue, but none of that is needed for the integrity allocations that either sits in the file system or at the very bottom of the I/O stack. Failing early means we'll do a fully waiting allocation from the mempool ->alloc callback which is usually much larger than required. Fix this by passing a gfp_t so that the file system path can pass GFP_NOFS and the auto-integrity code can pass GFP_NOIO, and don't modify the allocation type except for disabling warnings.

Currently, pci_create_legacy_files() and pci_remove_legacy_files() are no-op stubs. With legacy attributes now handled by static groups registered via pcibus_groups[], no call site needs them. Remove both functions, their declarations, and the call sites in pci_register_host_bridge(), pci_alloc_child_bus(), and pci_remove_bus(). Remove the pci_sysfs_init() late_initcall and sysfs_initialized. The late_initcall originally existed to create all the dynamic PCI sysfs files, but with both resource and legacy attributes now handled by static groups, it is no longer needed. Remove the legacy_io and legacy_mem fields from struct pci_bus which were used to track the dynamically allocated legacy attributes.

Currently, pci_create_sysfs_dev_files() and pci_remove_sysfs_dev_files() are no-op stubs. With both the generic and Alpha resource files now handled by static attribute groups, no platform needs dynamic per-device sysfs file creation. Remove both functions, their declarations, and the call sites in pci_bus_add_device() and pci_stop_dev(). Remove __weak pci_create_resource_files() and pci_remove_resource_files() stubs and their declarations in pci.h, as no architecture overrides them anymore. Remove the res_attr[] and res_attr_wc[] fields from struct pci_dev which were used to track dynamically allocated resource attributes. Finally, simplify pci_sysfs_init() to only handle legacy file creation under HAVE_PCI_LEGACY, removing the per-device loop and the HAVE_PCI_SYSFS_INIT helper added earlier.

On platforms with HAVE_PCI_MMAP or ARCH_GENERIC_PCI_MMAP_RESOURCE, resource files are now handled by static attribute groups registered via pci_dev_groups[]. Stub out the pci_create_sysfs_dev_files() and pci_remove_sysfs_dev_files(), as the dynamic resource file creation is no longer needed. Also, simplify pci_sysfs_init() on these platforms to only iterate buses for legacy attributes creation, skipping the per-device loop. Move the __weak stubs for pci_create_resource_files() and pci_remove_resource_files() into the #else branch since only platforms without HAVE_PCI_MMAP (such as Alpha architecture) still need them.

6 daysPCI/sysfs: Convert PCI resource files to static attributesKrzysztof Wilczyński
Currently, the PCI resource files (resourceN, resourceN_wc) are dynamically created by pci_create_sysfs_dev_files(), called from both pci_bus_add_device() and the pci_sysfs_init() late_initcall, with only a sysfs_initialized flag for synchronisation. This has caused warnings and boot panics when both paths race on the same device, e.g.: sysfs: cannot create duplicate filename '/devices/pci0000:3c/0000:3c:01.0/0000:3e:00.2/resource2' This is especially likely on Devicetree-based platforms, where the PCI host controllers are platform drivers that probe via the driver model, which can happen during or after the late_initcall. As such, pci_bus_add_device() and pci_sysfs_init() are more likely to overlap. Convert to static const attributes with three attribute groups (I/O, UC, WC), each with an .is_bin_visible() callback that checks resource flags, BAR length, and non_mappable_bars. A .bin_size() callback provides pci_resource_len() to the kernfs node for correct stat and lseek behaviour. As part of this conversion: - Rename pci_read_resource_io() and pci_write_resource_io() to pci_read_resource() and pci_write_resource() since the callbacks are no longer I/O-specific in the static attribute context. - Update __resource_resize_store() to use sysfs_create_groups() and sysfs_remove_groups(), which re-evaluates visibility and runs the .bin_size() callback for the static resource attribute groups. - Remove pci_create_resource_files(), pci_remove_resource_files(), and pci_create_attr() which are no longer needed. - Move the __weak stubs outside the #if guard so they remain available for callers converted in subsequent commits. Platforms that do not define the HAVE_PCI_MMAP macro or the ARCH_GENERIC_PCI_MMAP_RESOURCE macro, such as Alpha architecture, continue using their platform-specific resource file creation. For reference, the dynamic creation dates back to the pre-Git era: https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/drivers/pci/pci-sysfs.c?id=42298be0eeb5ae98453b3374c36161b05a46c5dc The write-combine support was added in commit 45aec1ae72fc ("x86: PAT export resource_wc in pci sysfs").

6 dayssoundwire: Move wait for initialisation helper to headerCharles Keepax
As SoundWire devices tend to enumerate on the bus after probe, drivers frequently need to wait for the device to initialise from common driver code. The common system is to split drivers into a core module and then a module for each communication bus. These two facts tend to cause Kconfig issues, the issue tends to be when SOUNDWIRE=m and DRIVER_I2C=y, this usually selects DRIVER=y. The driver code then wants to call sdw_slave_wait_for_init(), but this results in calling a module function from built in code. A depends on SOUNDWIRE | !SOUNDWIRE could be added to the end driver but this seems slightly off as it adds a lot of counter intuitive depends. A simpler solution is to make sdw_slave_wait_for_init() a static inline function. As part of doing this add a check for the slave device being NULL acknowledging that this is likely called from code that is shared between control buses. It does require dropping the call to sdw_show_ping_status() but this can be added back in end drivers that used it originally. Currently this is causing rand config issues on RT5682 and will soon also cause similar problems on cs42l43.

6 daysInput: stop force-feedback timer when unregistering input devicesDmitry Torokhov
Memoryless force-feedback devices use a timer to manage playback of effects. When a driver for such a device is unbound (or the device is unregistered for other reasons), the driver typically frees its private data synchronously. However, the input_dev structure (and its associated force-feedback structures, including the timer) is only freed when the last user closes the corresponding device node. If userspace keeps the device node open while the device is unregistered (e.g., during driver unbind), the force-feedback timer can still fire after the driver's private data has been freed. Introduce a new 'stop' callback to struct ff_device, and call it from input_unregister_device() before the device is deleted. Implement this callback for memoryless devices and synchronously shut down the timer to ensure it is stopped and cannot be rearmed once unregistration happens.

7 daysrtc: interface: Add rtc_read_next_alarm() to read next expiring timerMario Limonciello
Add a new function rtc_read_next_alarm() that reads the next expiring alarm from the RTC timerqueue. This is different from rtc_read_alarm(), which only reads the aie_timer. The wakealarm sysfs file programs the rtc->aie_timer, whereas the alarmtimer suspend routine programs its own timer into the RTC timerqueue. Both timers end up in the RTC's timerqueue, and the first expiring timer is what gets armed in the hardware. This new function allows code to query which alarm will actually fire next, regardless of which subsystem programmed it. This is needed by platform code that needs to program secondary timers based on the actual next wakeup time.

7 daysf2fs: validate orphan inode entry countWenjie Qi
f2fs_recover_orphan_inodes() trusts the orphan block entry_count when replaying orphan inodes from the checkpoint pack. A corrupted entry_count larger than F2FS_ORPHANS_PER_BLOCK makes the recovery loop read past the ino[] array and interpret footer or following data as inode numbers. On a crafted image, mounting an unpatched kernel can drive orphan recovery into f2fs_bug_on() and panic the kernel. Validate entry_count before consuming entries so corrupted checkpoint data fails the mount with -EFSCORRUPTED and requests fsck instead. Set ERROR_INCONSISTENT_ORPHAN as well, so the corruption reason can be recorded in the superblock s_errors[] field. This gives fsck a persistent hint even though mount-time orphan recovery failure may leave no chance to persist SBI_NEED_FSCK through a checkpoint.

git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab Pull more slab updates from Vlastimil Babka: - Introduce and wire up a new alloc_flags parameter for modifying slab-specific behavior without adding or reusing gfp flags. Also introduce slab_alloc_context to keep function parameter bloat in check. Both are similar to what the page allocator does. kmalloc_flags() exposes alloc_flags for mm-internal users. - SLAB_ALLOC_NOLOCK flag is used to implement kmalloc_nolock() behavior without relying on lack of __GFP_RECLAIM, which caused false positives with workarounds like fd3634312a04 ("debugobject: Make it work with deferred page initialization - again"). - SLAB_ALLOC_NO_RECURSE replaces __GFP_NO_OBJ_EXT, which could have been removed, but pending memory allocation profiling changes in mm tree have grown a new user - there is however a work ongoing to replace that too, so __GFP_NO_OBJ_EXT should eventually be removed.
