The patch titled
Subject: mm: memcg/slab: remove redundant check in memcg_accumulate_slabinfo()
has been removed from the -mm tree. Its filename was
mm-memcg-slab-remove-redundant-check-in-memcg_accumulate_slabinfo.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Roman Gushchin <guro@xxxxxx>
Subject: 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.
