[PATCH 16/16] mm: slab: remove redundant check in memcg_accumulate_slabinfo()

From: Roman Gushchin
Date: Thu Oct 17 2019 - 20:29:17 EST


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.
