linux-stable.git/drivers/gpu/drm/i915/i915_gpu_error.c, branch linux-rolling-stable Linux kernel stable tree treewide: Replace kmalloc with kmalloc_obj for non-scalar types 2026-02-21T09:02:28+00:00 Kees Cook kees@kernel.org 2026-02-21T07:49:23+00:00 69050f8d6d075dc01af7a5f2f550a8067510366f 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 <kees@kernel.org>

drm/{i915,xe}: convert i915 and xe display members into pointers 2025-05-16T08:15:16+00:00 Jani Nikula jani.nikula@intel.com 2025-05-07T15:22:54+00:00 96b451d53ae9760858c547081532b01038f00912 As the first step towards making struct intel_display an opaque pointer in i915 and xe drivers, convert the struct drm_i915_private and struct xe_device display members into pointers.

As the first step towards making struct intel_display an opaque pointer
in i915 and xe drivers, convert the struct drm_i915_private and struct
xe_device display members into pointers.

Initially, add temporary struct intel_display __display members, and
point display at it to avoid dynamic allocation. In the future, we can
drop this, and switch to dynamic allocation.

The conversion is done simply with sed:

sed -i 's/&\([a-zA-Z0-9_>.-]*\)\(dev_priv\|i915\|xe\)->display\([^.]\)/\1\2->display\3/g' \
    $(git ls-files -- drivers/gpu/drm/i915 drivers/gpu/drm/xe)

sed -i 's/\(dev_priv\|i915\|xe\)->display\./\1->display->/g' \
    $(git ls-files -- drivers/gpu/drm/i915 drivers/gpu/drm/xe)

With a couple of manual tweaks on top.

v2: Initialize i915->display also in selftest mock_gem_device()
