[PATCH] docs: rust: rbtree: fix incorrect description for `peek_next`

by WeiKang Guo

The documentation for `Cursor::peek_next` incorrectly describes it as "Access the previous node without moving the cursor" when it actually accesses the next node. Update the description to correctly state "Access the next node without moving the cursor" to match the function name and implementation.

[PATCH] leds: led-class: Only Add LED to leds_list when it is fully ready

by Hans de Goede

Before this change the LED was added to leds_list before led_init_core() gets called adding it the list before led_classdev.set_brightness_work gets initialized. This leaves a window where led_trigger_register() of a LED's default trigger will call led_trigger_set() which calls led_set_brightness() which in turn will end up queueing the *uninitialized* led_classdev.set_brightness_work. This race gets hit by the lenovo-thinkpad-t14s EC driver which registers 2 LEDs with a default trigger provided by snd_ctl_led.ko in quick succession. The first led_classdev_register() causes an async modprobe of snd_ctl_led to run and that async modprobe manages to exactly hit the window where the second LED is on the leds_list without led_init_core() being called for it, resulting in: ------------[ cut here ]------------ WARNING: CPU: 11 PID: 5608 at kernel/workqueue.c:4234 __flush_work+0x344/0x390 Hardware name: LENOVO 21N2S01F0B/21N2S01F0B, BIOS N42ET93W (2.23 ) 09/01/2025 ...

[PATCH] input: lkkbd: cancel pending work before freeing device

by Minseong Kim

lkkbd_interrupt() schedules lk->tq with schedule_work(), and the work handler lkkbd_reinit() dereferences the lkkbd structure and its serio/input_dev fields. lkkbd_disconnect() frees the lkkbd structure without cancelling this work, so the work can run after the structure has been freed, leading to a potential use-after-free. Cancel the pending work in lkkbd_disconnect() before unregistering and freeing the device, following the same pattern as sunkbd.

[tip: x86/urgent] x86/acpi/boot: Correct acpi_is_processor_usable() check again

by tip-bot2 for Yazen Ghannam

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 4368a3b96c427ea3299be8cedb28684ba4157529 Gitweb: https://git.kernel.org/tip/4368a3b96c427ea3299be8cedb28684ba4157529 Author: Yazen Ghannam <yazen.ghannam(a)amd.com> AuthorDate: Tue, 11 Nov 2025 14:53:57 Committer: Ingo Molnar <mingo(a)kernel.org> CommitterDate: Fri, 12 Dec 2025 09:38:30 +01:00 x86/acpi/boot: Correct acpi_is_processor_usable() check again ACPI v6.3 defined a new "Online Capable" MADT LAPIC flag. This bit is used in conjunction with the "Enabled" MADT LAPIC flag to determine if a CPU can be enabled/hotplugged by the OS after boot. Before the new bit was defined, the "Enabled" bit was explicitly described like this (ACPI v6.0 wording provided): "If zero, this processor is unusable, and the operating system support will not attempt to use it" This means that CPU hotplug (based on MADT) is not possible. Many BIOS implementations follow this guidance. They may include LAPIC entries in MADT for unavailable CPUs, but since these entries are marked with "Enabled=0" it is expected that the OS will completely ignore these entries. However, QEMU will do the same (include entries with "Enabled=0") for the purpose of allowing CPU hotplug within the guest. Comment from QEMU function pc_madt_cpu_entry(): /* ACPI spec says that LAPIC entry for non present * CPU may be omitted from MADT or it must be marked * as disabled. However omitting non present CPU from * MADT breaks hotplug on linux. So possible CPUs * should be put in MADT but kept disabled. */ Recent Linux topology changes broke the QEMU use case. A following fix for the QEMU use case broke bare metal topology enumeration. Rework the Linux MADT LAPIC flags check to allow the QEMU use case only for guests and to maintain the ACPI spec behavior for bare metal. Remove an unnecessary check added to fix a bare metal case introduced by the QEMU "fix".
