__add_to_page_cache_locked() after mem_cgroup_try_charge_cache() uses mem_cgroup_cancel_charge() in one of the error paths. This may lead to leaking a few memcg->cache charges.
Use mem_cgroup_cancel_cache_charge() to fix this. https://jira.sw.ru/browse/PSBM-121046 Signed-off-by: Andrey Ryabinin <aryabi...@virtuozzo.com> --- mm/filemap.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/filemap.c b/mm/filemap.c index 53db13f236da..2bd5ca4e7528 100644 --- a/mm/filemap.c +++ b/mm/filemap.c @@ -732,7 +732,7 @@ static int __add_to_page_cache_locked(struct page *page, error = radix_tree_maybe_preload(gfp_mask & GFP_RECLAIM_MASK); if (error) { if (!huge) - mem_cgroup_cancel_charge(page, memcg); + mem_cgroup_cancel_cache_charge(page, memcg); return error; } -- 2.26.2 _______________________________________________ Devel mailing list Devel@openvz.org https://lists.openvz.org/mailman/listinfo/devel
