treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

apm-emulation: remove unused __apm_get_power_status

2025-10-22T05:59:57+00:00

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.

apm-emulation: hide an unused variable

2025-04-17T08:56:11+00:00

The driver_version variable is only used inside of an #ifdef block, which leads to a W=1 warning: drivers/char/apm-emulation.c:144:19: error: 'driver_version' defined but not used [-Werror=unused-const-variable=] Move this into the function using it.

Add SPDX license identifiers to all files which: - Have no license information of any form - Have MODULE_LICENCE("GPL*") inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only.

proc: introduce proc_create_single{,_data}

Variants of proc_create{,_data} that directly take a seq_file show callback and drastically reduces the boilerplate code in the callers. All trivial callers converted over. Signed-off-by: Christoph Hellwig

vfs: do bulk POLL* -> EPOLL* replacement

2018-02-11T22:34:03+00:00

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^$[^\"]*$$\$/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro Signed-off-by: Linus Torvalds
