From e55b9f96860f6c6026cff97966a740576285e07b Mon Sep 17 00:00:00 2001 From: Johannes Weiner Date: Mon, 26 Sep 2022 09:57:04 -0400 Subject: mm: memcontrol: drop dead CONFIG_MEMCG_SWAP config symbol Since 2d1c498072de ("mm: memcontrol: make swap tracking an integral part of memory control"), CONFIG_MEMCG_SWAP hasn't been a user-visible config option anymore, it just means CONFIG_MEMCG && CONFIG_SWAP. Update the sites accordingly and drop the symbol. [ While touching the docs, remove two references to CONFIG_MEMCG_KMEM, which hasn't been a user-visible symbol for over half a decade. ] Link: https://lkml.kernel.org/r/20220926135704.400818-5-hannes@cmpxchg.org Signed-off-by: Johannes Weiner Acked-by: Shakeel Butt Cc: Hugh Dickins Cc: Michal Hocko Cc: Roman Gushchin Signed-off-by: Andrew Morton --- mm/memcontrol.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'mm/memcontrol.c') diff --git a/mm/memcontrol.c b/mm/memcontrol.c index 76bb0a18a2f3..61e05fc281fb 100644 --- a/mm/memcontrol.c +++ b/mm/memcontrol.c @@ -3423,7 +3423,7 @@ void split_page_memcg(struct page *head, unsigned int nr) css_get_many(&memcg->css, nr - 1); } -#ifdef CONFIG_MEMCG_SWAP +#ifdef CONFIG_SWAP /** * mem_cgroup_move_swap_account - move swap charge and swap_cgroup's record. * @entry: swap entry to be moved @@ -7296,7 +7296,7 @@ static int __init mem_cgroup_init(void) } subsys_initcall(mem_cgroup_init); -#ifdef CONFIG_MEMCG_SWAP +#ifdef CONFIG_SWAP static struct mem_cgroup *mem_cgroup_id_get_online(struct mem_cgroup *memcg) { while (!refcount_inc_not_zero(&memcg->id.ref)) { @@ -7788,4 +7788,4 @@ static int __init mem_cgroup_swap_init(void) } subsys_initcall(mem_cgroup_swap_init); -#endif /* CONFIG_MEMCG_SWAP */ +#endif /* CONFIG_SWAP */ -- cgit v1.2.1
