drm/vmwgfx: fix kernel-doc warnings in vmwgfx_drv.h

2026-03-16T15:39:22Z

Fix 45+ kernel-doc warnings in vmwgfx_drv.h: - spell a struct name correctly - don't have structs between kernel-doc and its struct - end description of struct members with ':' - start all kernel-doc lines with " *" - mark private struct member and enum value with "private:" - add kernel-doc for enum vmw_dma_map_mode - add missing struct member comments - add missing function parameter comments - convert "/**" to "/*" for non-kernel-doc comments - add missing "Returns:" comments for several functions - correct a function parameter name to eliminate kernel-doc warnings (examples): Warning: drivers/gpu/drm/vmwgfx/vmwgfx_drv.h:128 struct vmw_bo; error: Cannot parse struct or union!

dma-buf: inline spinlock for fence protection v5

2026-02-23T15:14:19Z

Implement per-fence spinlocks, allowing implementations to not give an external spinlock to protect the fence internal state. Instead a spinlock embedded into the fence structure itself is used in this case. Shared spinlocks have the problem that implementations need to guarantee that the lock lives at least as long all fences referencing them. Using a per-fence spinlock allows completely decoupling spinlock producer and consumer life times, simplifying the handling in most use cases. v2: improve naming, coverage and function documentation v3: fix one additional locking in the selftests v4: separate out some changes to make the patch smaller, fix one amdgpu crash found by CI systems v5: improve comments Signed-off-by: Christian König Reviewed-by: Boris Brezillon Link: https://lore.kernel.org/r/20260219160822.1529-5-christian.koenig@amd.com

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00Z

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

2026-02-21T09:02:28Z

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
