Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51+00:00

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. Signed-off-by: Linus Torvalds

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

ALSA: vmaster: Relax __free() variable declarations

2025-12-17T09:08:30+00:00

We used to have a variable declaration with __free() initialized with NULL. This was to keep the old coding style rule, but recently it's relaxed and rather recommends to follow the new rule to declare in place of use for __free() -- which avoids potential deadlocks or UAFs with nested cleanups. Although the current code has no bug, per se, let's follow the new standard and move the declaration to the place of assignment (or directly assign the allocated result) instead of NULL initializations.

ALSA: vmaster: Return error for invalid input values

2024-06-18T10:00:18+00:00

So far the vmaster code has been tolerant about the input values and accepts any values by correcting internally. But now our own selftest starts complaining about this behavior, so let's be picky and change the behavior to return -EINVAL for invalid input values instead.

ALSA: vmaster: Use automatic cleanup of kfree()

2024-02-23T09:57:30+00:00

There are common patterns where a temporary buffer is allocated and freed at the exit, and those can be simplified with the recent cleanup mechanism via __free(kfree). No functional changes, only code refactoring. Signed-off-by: Takashi Iwai Link: https://lore.kernel.org/r/20240222111509.28390-6-tiwai@suse.de

ALSA: vmaster: Add snd_ctl_add_followers() helper

Add a new helper to add multiple vmaster followers in a shot. The same function was open-coded in various places, and this helper replaces them. Link: https://lore.kernel.org/r/20230721071643.3631-2-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: core: Fix missing return value comments for kernel docs

ALSA: Replace the word "slave" in vmaster API

2020-07-20T08:10:47+00:00

Follow the recent inclusive terminology guidelines and replace the word "slave" in vmaster API. I chose the word "follower" at this time since it seems fitting for the purpose. Note that the word "master" is kept in API, since it refers rather to audio master volume control. Also, while we're at it, a typo in comments is corrected, too.
