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

dma-fence: Use a flag for 64-bit seqnos

2025-06-03T16:38:04+00:00

With the goal of reducing the need for drivers to touch (and dereference) fence->ops, we move the 64-bit seqnos flag from struct dma_fence_ops to the fence->flags. Drivers which were setting this flag are changed to use new dma_fence_init64() instead of dma_fence_init(). v2: * Streamlined init and added kerneldoc. * Rebase for amdgpu userq which landed since.

drm/amdgpu: fix use-after-unlock in eviction fence destroy

2025-05-16T17:38:10+00:00

The eviction fence destroy path incorrectly calls dma_fence_put() on evf_mgr->ev_fence after releasing the ev_fence_lock. This introduces a potential use-after-unlock or race because another thread concurrently modifies evf_mgr->ev_fence. Fix this by grabbing a local reference to evf_mgr->ev_fence under the lock and using that for dma_fence_put() after waiting.
