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

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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: firewire: use nonatomic PCM operation

2024-09-04T12:51:54Z

In the former commits, the callback of isochronous context runs on usual work process. In the case, ALSA PCM device has a flag, nonatomic, to acquire mutex lock instead of spin lock for PCM substream group. This commit uses the flag. It has an advantage in the case that ALSA PCM application uses the large size of intermediate buffer, since it takes too long time even in tasklet softIRQ to process many of isochronous packets, then result in the delay of system event due to disabled IRQ so long. It is avertible to switch to nonatomic operation.

ALSA: firewire: Use -y instead of -objs in Makefile

2024-05-08T16:18:03Z

*-objs suffix is reserved rather for (user-space) host programs while usually *-y suffix is used for kernel drivers (although *-objs works for that purpose for now). Let's correct the old usages of *-objs in Makefiles.

ALSA: firewire: Fix -Wformat-truncation warning for MIDI stream names

2023-09-15T11:22:06Z

The compile warnings at filling MIDI stream name strings are all false-positive; the number of streams can't go so high. For suppressing the warning, replace snprintf() with scnprintf(). As stated in the above, truncation doesn't matter.
