Subject: [PATCH v4 16/19] mm: memcg/slab: remove redundant check in memcg_accumulate_slabinfo()
Date:   Tue, 26 May 2020 14:42:24 -0700

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.
