Subject: [PATCH 0/2] mm, slab: Extend vm/drop_caches to shrink kmem slabs
Date:   Mon, 24 Jun 2019 13:42:17 -0400
Message-Id: <20190624174219.25513-1-longman@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The purpose of this patchset is to allow system administrators to have
the ability to shrink all the kmem slabs in order to free up memory
and get a more accurate picture of how many slab objects are actually
being used.

Patch 1 adds a new memcg_iterate_all() that is used by the patch 2 to
iterate on all the memory cgroups.

Waiman Long (2):
  mm, memcontrol: Add memcg_iterate_all()
  mm, slab: Extend vm/drop_caches to shrink kmem slabs
