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

convert rpc_pipefs

Just use d_make_persistent() + dput() (and fold the latter into simple_finish_creating()) and that's it... NOTE: pipe->dentry is a borrowed reference - it does not contribute to dentry refcount. Signed-off-by: Al Viro

rpc_new_dir(): the last argument is always NULL

2025-07-03T02:44:55+00:00

All callers except the one in rpc_populate() pass explicit NULL there; rpc_populate() passes its last argument ('private') instead, but in the only call of rpc_populate() that creates any subdirectories (when creating fixed subdirectories of root) private itself is NULL.
