[PATCH v4 16/19] mm: memcg/slab: remove redundant check in memcg_accumulate_slabinfo()

From: Roman Gushchin
Date: Tue May 26 2020 - 17:44:02 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.
