Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using git grep -l '\

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/msm: rd dumping support for sparse

As with devcoredump, we need to iterate the VMAs to figure out what to dump. Signed-off-by: Rob Clark Signed-off-by: Rob Clark Tested-by: Antonino Maniscalco Reviewed-by: Antonino Maniscalco Patchwork: https://patchwork.freedesktop.org/patch/661510/

[tree-wide] finally take no_llseek out

2024-09-27T15:18:43+00:00

no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

drm/msm: don't create GPU-related debugfs files with no GPU present

If there is no GPU present, skip creation of the GPU-related debugfs files, making the MSM's debugfs more usable. Signed-off-by: Dmitry Baryshkov Patchwork: https://patchwork.freedesktop.org/patch/561742/ Signed-off-by: Rob Clark

drm/msm: Use drm_gem_object in submit bos table

drm/msm: Move cmdstream dumping out of sched kthread

2023-06-10T13:46:12+00:00

This is something that can block for arbitrary amounts of time as userspace consumes from the FIFO. So we don't really want this to be in the fence signaling path. Signed-off-by: Rob Clark Patchwork: https://patchwork.freedesktop.org/patch/532617/

drm/msm/rd: Fix FIFO-full deadlock

2022-08-15T17:19:53+00:00

If the previous thing cat'ing $debugfs/rd left the FIFO full, then subsequent open could deadlock in rd_write() (because open is blocked, not giving a chance for read() to consume any data in the FIFO). Also it is generally a good idea to clear out old data from the FIFO.
