The quilt patch titled Subject: mm: memcg: declare do_memsw_account inline has been removed from the -mm tree. Its filename was mm-memcg-declare-do_memsw_account-inline.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: John Sperbeck <jsperbeck@xxxxxxxxxx> Subject: mm: memcg: declare do_memsw_account inline Date: Thu, 28 Nov 2024 12:39:59 -0800 In commit 66d60c428b23 ("mm: memcg: move legacy memcg event code into memcontrol-v1.c"), the static do_memsw_account() function was moved from a .c file to a .h file. Unfortunately, the traditional inline keyword wasn't added. If a file (e.g., a unit test) includes the .h file, but doesn't refer to do_memsw_account(), it will get a warning like: mm/memcontrol-v1.h:41:13: warning: unused function 'do_memsw_account' [-Wunused-function] 41 | static bool do_memsw_account(void) | ^~~~~~~~~~~~~~~~ Link: https://lkml.kernel.org/r/20241128203959.726527-1-jsperbeck@xxxxxxxxxx Fixes: 66d60c428b23 ("mm: memcg: move legacy memcg event code into memcontrol-v1.c") Signed-off-by: John Sperbeck <jsperbeck@xxxxxxxxxx> Acked-by: Roman Gushchin <roman.gushchin@xxxxxxxxx> Cc: Johannes Weiner <hannes@xxxxxxxxxxx> Cc: Michal Hocko <mhocko@xxxxxxxxxx> Cc: Muchun Song <muchun.song@xxxxxxxxx> Cc: Shakeel Butt <shakeel.butt@xxxxxxxxx> Cc: <stable@xxxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- mm/memcontrol-v1.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/mm/memcontrol-v1.h~mm-memcg-declare-do_memsw_account-inline +++ a/mm/memcontrol-v1.h @@ -38,7 +38,7 @@ void mem_cgroup_id_put_many(struct mem_c iter = mem_cgroup_iter(NULL, iter, NULL)) /* Whether legacy memory+swap accounting is active */ -static bool do_memsw_account(void) +static inline bool do_memsw_account(void) { return !cgroup_subsys_on_dfl(memory_cgrp_subsys); } _ Patches currently in -mm which might be from jsperbeck@xxxxxxxxxx are
