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

ocfs2: constify struct ocfs2_stack_operations

2024-06-25T05:25:10+00:00

"struct ocfs2_stack_operations" are not modified in this driver. Constifying this structure moves some data to a read-only section, so increase overall security. In order to do it, "struct ocfs2_stack_plugin" also needs to be adjusted to this new const qualifier. On a x86_64, with allmodconfig: Before: ====== text data bss dec hex filename 6241 644 0 6885 1ae5 fs/ocfs2/stack_o2cb.o After: ===== text data bss dec hex filename 6337 548 0 6885 1ae5 fs/ocfs2/stack_o2cb.o Link: https://lkml.kernel.org/r/f52dab89ee0049ec6271de29183a781efbb275ab.1718398605.git.christophe.jaillet@wanadoo.fr Signed-off-by: Christophe JAILLET Cc: Mark Fasheh Cc: Joel Becker Cc: Junxiao Bi Cc: Joseph Qi Cc: Changwei Ge Cc: Gang He Cc: Jun Piao Signed-off-by: Andrew Morton

treewide: remove editor modelines and cruft

2021-05-07T07:26:34+00:00

The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files." I recently receive a patch to explicitly add a new one. Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups. It is even nicer if scripts/checkpatch.pl can check it. If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.

ocfs2: map flags directly in flags_to_o2dlm()

2021-04-30T18:20:35+00:00

Use macro map_flag() is tricky and coccicheck outputs the following warning: fs/ocfs2/stack_o2cb.c:69:5-16: Unneeded variable: "o2dlm_flags" So map flags directly in flags_to_o2dlm() to make coccicheck happy. And remove BUG_ON() here as well to simplify code since it runs well a long time.

ocfs2: pass ocfs2_cluster_connection to ocfs2_this_node

2014-01-22T00:19:41+00:00

This is done to differentiate between using and not using controld and use the connection information accordingly. We need to be backward compatible. So, we use a new enum ocfs2_connection_type to identify when controld is used and when it is not.
