[Devel] [PATCH rh7] mm/filemap: fix potential memcg->cache charge leak

__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
