2026-02-21	Convert 'alloc_obj' family to use the new default GFP_KERNEL argument	Linus Torvalds
	This was done entirely with mindless brute force, using git grep -l '\<k[vmz]alloc_objs(., GFP_KERNEL)' \| xargs sed -i 's/\(alloc_objs(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21	treewide: Replace kmalloc with kmalloc_obj for non-scalar types	Kees Cook
	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>
2023-11-23	drm/imagination: Implement job submission and scheduling	Sarah Walker
	Implement job submission ioctl. Job scheduling is implemented using drm_sched. Jobs are submitted in a stream format. This is intended to allow the UAPI data format to be independent of the actual FWIF structures in use, which vary depending on the GPU in use. The stream formats are documented at: https://gitlab.freedesktop.org/mesa/mesa/-/blob/f8d2b42ae65c2f16f36a43e0ae39d288431e4263/src/imagination/csbgen/rogue_kmd_stream.xml Changes since v8: - Updated for upstreamed DRM scheduler changes - Removed workaround code for the pending_list previously being updated after run_job() returned - Fixed null deref in pvr_queue_cleanup_fw_context() for bad stream ptr given to create_context ioctl - Corrected license identifiers Changes since v7: - Updated for v8 "DRM scheduler changes for XE" patchset Changes since v6: - Fix fence handling in pvr_sync_signal_array_add() - Add handling for SUBMIT_JOB_FRAG_CMD_DISABLE_PIXELMERGE flag - Fix missing dma_resv locking in job submit path Changes since v5: - Fix leak in job creation error path Changes since v4: - Use a regular workqueue for job scheduling Changes since v3: - Support partial render jobs - Add job timeout handler - Split sync handling out of job code - Use drm_dev_{enter,exit} Changes since v2: - Use drm_sched for job scheduling Co-developed-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Co-developed-by: Donald Robson <donald.robson@imgtec.com> Signed-off-by: Donald Robson <donald.robson@imgtec.com> Signed-off-by: Sarah Walker <sarah.walker@imgtec.com> Link: https://lore.kernel.org/r/c98dab7a5f5fb891fbed7e4990d19b5d13964365.1700668843.git.donald.robson@imgtec.com Signed-off-by: Maxime Ripard <mripard@kernel.org>
