From 50591183fa86c4436f6408c6b702af5e4de7524d Mon Sep 17 00:00:00 2001 From: Roman Gushchin Date: Wed, 1 Apr 2020 21:06:43 -0700 Subject: [PATCH] mm: kmem: cleanup memcg_kmem_uncharge_memcg() arguments Drop the unused page argument and put the memcg pointer at the first place. This make the function consistent with its peers: __memcg_kmem_uncharge_memcg(), memcg_kmem_charge_memcg(), etc. Signed-off-by: Roman Gushchin Signed-off-by: Andrew Morton Reviewed-by: Shakeel Butt Acked-by: Johannes Weiner Cc: Michal Hocko Cc: Vladimir Davydov Link: http://lkml.kernel.org/r/20200109202659.752357-3-guro@fb.com Signed-off-by: Linus Torvalds --- include/linux/memcontrol.h | 4 ++-- mm/slab.h | 2 +- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/include/linux/memcontrol.h b/include/linux/memcontrol.h index f1542d6558c2..13b5d70b8b0e 100644 --- a/include/linux/memcontrol.h +++ b/include/linux/memcontrol.h @@ -1414,8 +1414,8 @@ static inline int memcg_kmem_charge_memcg(struct mem_cgroup *memcg, gfp_t gfp, return 0; } -static inline void memcg_kmem_uncharge_memcg(struct page *page, int order, - struct mem_cgroup *memcg) +static inline void memcg_kmem_uncharge_memcg(struct mem_cgroup *memcg, + int order) { if (memcg_kmem_enabled()) __memcg_kmem_uncharge_memcg(memcg, 1 << order); diff --git a/mm/slab.h b/mm/slab.h index c4c93e991250..e7da63fb8211 100644 --- a/mm/slab.h +++ b/mm/slab.h @@ -395,7 +395,7 @@ static __always_inline void memcg_uncharge_slab(struct page *page, int order, if (likely(!mem_cgroup_is_root(memcg))) { lruvec = mem_cgroup_lruvec(memcg, page_pgdat(page)); mod_lruvec_state(lruvec, cache_vmstat_idx(s), -(1 << order)); - memcg_kmem_uncharge_memcg(page, order, memcg); + memcg_kmem_uncharge_memcg(memcg, order); } else { mod_node_page_state(page_pgdat(page), cache_vmstat_idx(s), -(1 << order)); -- 2.30.2
