Date: Tue, 26 May 2020 14:42:24 -0700 From: Roman Gushchin <guro@...com> To: Andrew Morton <akpm@...ux-foundation.org>, Christoph Lameter <cl@...ux.com> CC: Johannes Weiner <hannes@...xchg.org>, Michal Hocko <mhocko@...nel.org>, Shakeel Butt <shakeelb@...gle.com>, <linux-mm@...ck.org>, Vlastimil Babka <vbabka@...e.cz>, <kernel-team@...com>, <linux-kernel@...r.kernel.org>, Roman Gushchin <guro@...com> Subject: [PATCH v4 16/19] mm: memcg/slab: remove redundant check in memcg_accumulate_slabinfo() memcg_accumulate_slabinfo() is never called with a non-root kmem_cache as a first argument, so the is_root_cache(s) check is redundant and can be removed without any functional change.
