Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. 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

drm/amd/ras: Reduce stack usage in amdgpu_virt_ras_get_cper_records()

2025-12-10T22:37:50+00:00

amdgpu_virt_ras_get_cper_records() was using a large stack array of ras_log_info pointers. This contributed to the frame size warning on this function. Replace the fixed-size stack array: struct ras_log_info *trace[MAX_RECORD_PER_BATCH]; with a heap-allocated array using kcalloc(). We free the trace buffer together with out_buf on all exit paths. If allocation of trace or out_buf fails, we return a generic RAS error code. This reduces stack usage and keeps the runtime behaviour unchanged.

drm/amd/ras: Reduce stack usage in ras_umc_handle_bad_pages()

2025-12-08T19:25:37+00:00

ras_umc_handle_bad_pages() function used a large local array: struct eeprom_umc_record records[MAX_ECC_NUM_PER_RETIREMENT]; Move this array off the stack by allocating it with kcalloc() and freeing it before return. This reduces the stack frame size of ras_umc_handle_bad_pages() and avoids the frame size warning. Fixes the below: drivers/gpu/drm/amd/amdgpu/../ras/rascore/ras_umc.c:498:5: warning: stack frame size (1208) exceeds limit (1024) in 'ras_umc_handle_bad_pages' [-Wframe-larger-than] v2: Removed the duplicate ras_umc_get_new_records() invocation.
