kernel/linux.git/drivers/gpu/drm/ttm/ttm_sys_manager.c, branch linux-7.0.yLinux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=linux-7.0.y2026-02-22T01:09:51+00:00Convert 'alloc_obj' family to use the new default GFP_KERNEL argument2026-02-22T01:09:51+00:00Linus Torvaldstorvalds@linux-foundation.org2026-02-22T00:37:42+00:00urn:sha1:bf4afc53b77aeaa48b5409da5c8da6bb4eff7f43
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.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types2026-02-21T09:02:28+00:00Kees Cookkees@kernel.org2026-02-21T07:49:23+00:00urn:sha1:69050f8d6d075dc01af7a5f2f550a8067510366f
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 *".

drm/ttm: add back a reference to the bdev to the res manager2022-01-26T14:29:24+00:00Christian Königchristian.koenig@amd.com2021-08-30T07:22:06+00:00urn:sha1:3f268ef06f8cf3c481dbd5843d564f5170c6df54
It is simply a lot cleaner to have this around instead of adding
the device throughout the call chain.
