2025-10-22apm-emulation: remove unused __apm_get_power_statusAhelenia Ziemiańska
The API for apm_get_power_status is "call it if it isn't NULL", except it's also initialised with a no-op __apm_get_power_status. This was added alongside apm_get_power_status in 2007. The apm_get_power_status symbol is used in these files: arch/arm/mach-pxa/sharpsl_pm.c:extern void (*apm_get_power_status)(struct apm_power_info *); arch/arm/mach-pxa/sharpsl_pm.c: apm_get_power_status = sharpsl_apm_get_power_status; arch/sh/boards/mach-hp6xx/hp6xx_apm.c: apm_get_power_status = hp6x0_apm_get_power_status; drivers/char/apm-emulation.c:void (*apm_get_power_status)(struct apm_power_info *) = __apm_get_power_status; drivers/char/apm-emulation.c:EXPORT_SYMBOL(apm_get_power_status); drivers/char/apm-emulation.c: if (apm_get_power_status) drivers/char/apm-emulation.c: apm_get_power_status(&info); drivers/macintosh/apm_emu.c: apm_get_power_status = pmu_apm_get_power_status; drivers/macintosh/apm_emu.c: if (apm_get_power_status == pmu_apm_get_power_status) drivers/macintosh/apm_emu.c: apm_get_power_status = NULL; drivers/power/supply/apm_power.c: apm_get_power_status = apm_battery_apm_get_power_status; drivers/power/supply/apm_power.c: apm_get_power_status = NULL; include/linux/apm-emulation.h:extern void (*apm_get_power_status)(struct apm_power_info *); All of them are compatible with the API (post-remove UAFs notwithstanding) and don't even read it except to compare with their own values; on a cursory glance this doesn't seem to have ever not been the case.

2025-10-22LICENSES: Add modern form of the LGPL-2.1 tags to the usage guide sectionThomas Huth
The modern forms of the LGPL-2.1 tags have already been added as valid a long time ago, see commit bc128349588d5 ("LICENSES/LGPL-2.1: Add LGPL-2.1-or-later as valid identifiers"). However, the information is still missing in the "Usage-Guide" section, so it can currently be confusing whether these tags are allowed in new files or not. Thus add the tags to the usage guide section, too, to make this clear (similar to what we do in the GPL-2.0 file already).

2025-10-22rust: replace `CStr` with `core::ffi::CStr`Tamir Duberstein
`kernel::ffi::CStr` was introduced in commit d126d2380131 ("rust: str: add `CStr` type") in November 2022 as an upstreaming of earlier work that was done in May 2021[0]. That earlier work, having predated the inclusion of `CStr` in `core`, largely duplicated the implementation of `std::ffi::CStr`. `std::ffi::CStr` was moved to `core::ffi::CStr` in Rust 1.64 in September 2022. Hence replace `kernel::str::CStr` with `core::ffi::CStr` to reduce our custom code footprint, and retain needed custom functionality through an extension trait. Add `CStr` to `ffi` and the kernel prelude.

2025-10-22Revert "fs/9p: Refresh metadata in d_revalidate for uncached mode too"Dominique Martinet
This reverts commit 290434474c332a2ba9c8499fe699c7f2e1153280. That commit broke cache=mmap, a mode that doesn't cache metadata, but still has writeback cache. In commit 290434474c33 ("fs/9p: Refresh metadata in d_revalidate for uncached mode too") we considered metadata cache to be enough to not look at the server, but in writeback cache too looking at the server size would make the vfs consider the file has been truncated before the data has been flushed out, making the following repro fail (nothing is ever read back, the resulting file ends up with no data written) ``` #include <fcntl.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> char buf[4096]; int main(int argc, char *argv[]) { int ret, i; int fdw, fdr; if (argc < 2) return 1; fdw = openat(AT_FDCWD, argv[1], O_RDWR|O_CREAT|O_EXCL|O_CLOEXEC, 0600); if (fdw < 0) { fprintf(stderr, "cannot open fdw\n"); return 1; } write(fdw, buf, sizeof(buf)); fdr = openat(AT_FDCWD, argv[1], O_RDONLY|O_CLOEXEC); if (fdr < 0) { fprintf(stderr, "cannot open fdr\n"); close(fdw); return 1; } for (i = 0; i < 10; i++) { ret = read(fdr, buf, sizeof(buf)); fprintf(stderr, "i: %d, read returns %d\n", i, ret); } close(fdr); close(fdw); return 0; } ``` There is a fix for this particular reproducer but it looks like there are other problems around metadata refresh (e.g. around file rename), so revert this to avoid d_revalidate in uncached mode for now.

Introduce a `fmt!` macro which wraps all arguments in `kernel::fmt::Adapter` and a `kernel::fmt::Display` trait.

2025-10-21net: dlink: use dev_kfree_skb_any instead of dev_kfree_skbYeounsu Moon
Replace `dev_kfree_skb()` with `dev_kfree_skb_any()` in `start_xmit()` which can be called from netpoll (hard IRQ) and from other contexts. Also, `np->link_status` can be changed at any time by interrupt handler. <idle>-0 [011] dNh4. 4541.754603: start_xmit <-netpoll_start_xmit <idle>-0 [011] dNh4. 4541.754622: <stack trace> => [FTRACE TRAMPOLINE] => start_xmit => netpoll_start_xmit => netpoll_send_skb => write_msg => console_flush_all => console_unlock => vprintk_emit => _printk => rio_interrupt => __handle_irq_event_percpu => handle_irq_event => handle_fasteoi_irq => __common_interrupt => common_interrupt => asm_common_interrupt => mwait_idle => default_idle_call => do_idle => cpu_startup_entry => start_secondary => common_startup_64 This issue can occur when the link state changes from off to on (e.g., plugging or unplugging the LAN cable) while transmitting a packet. If the skb has a destructor, a warning message may be printed in this situation. -> consume_skb (dev_kfree_skb()) -> __kfree_skb() -> skb_release_all() -> skb_release_head_state(skb) if (skb->destructor) { DEBUG_NET_WARN_ON_ONCE(in_hardirq()); skb->destructor(skb); } Found by inspection.

2025-10-21Merge patch series "Enhance UFS Mediatek Driver"Martin K. Petersen
Peter Wang <peter.wang@mediatek.com says>: Improves the UFS Mediatek driver by correcting clock scaling with PM QoS, and adjusting power management flows. It addresses shutdown/suspend race conditions, and removes redundant functions. Support for new platforms is added with the MMIO_OTSD_CTRL register, and MT6991 performance is optimized with MRTT and random improvements. These changes collectively enhance driver performance, stability, and compatibility. Changes since v1: 1. Remove two patches that will be fixed in UFS core. - ufs: host: mediatek: Fix runtime suspend error deadlock - ufs: host: mediatek: Enable interrupts for MCQ mode 2. Use hba->shutting_down instead of ufshcd_is_user_access_allowed v1: https://patch.msgid.link/20250918104000.208856-1-peter.wang@mediatek.com Link: https://patch.msgid.link/20250924094527.2992256-1-peter.wang@mediatek.com Signed-off-by: Martin K.

2025-10-21scsi: ufs: host: mediatek: Add support for new platform with MMIO_OTSD_CTRPeter Wang
Introduce support for a new UFS Mediatek platform by adding the REG_UFS_UFS_MMIO_OTSD_CTRL register. This update includes checks for legacy platforms and uses the new register to replace debug selection and handle specific operations. The changes ensure compatibility across different hardware versions and prevent potential issues with debug usage on newer platforms. Additional updates include error logging improvements during link setup for newer and legacy platforms, ensuring proper event logging and debugging.

2025-10-21eth: 3c515: replace cleanup_module with __exitShi Hao
update old legacy cleanup_module from the file with __exit module as per kernel code practices and restore the #ifdef MODULE condition to allow successful compilation as a built -in driver. The file had an old cleanup_module still in use which could be updated with __exit module function although its init_module is indeed newer however the cleanup_module was still using the older version of exit. To set proper exit module function replace cleanup_module with __exit corkscrew_exit_module to align it to the kernel code consistency.
