Subject: [PATCH 04/12] mm/vmscan: push zone pointer into shrink_page_list()
Date: Thu, 26 Apr 2012 11:54:04 +0400	[thread overview]
Message-ID: <20120426075404.18961.18621.stgit@zurg> (raw)
In-Reply-To: <20120426074632.18961.17803.stgit@zurg>

It doesn't need pointer to cgroup, pointer to zone is enough.
This patch also kills "mz" argument of page_check_references(), it unused after
"mm: memcg: count pte references from every member of the reclaimed hierarch"
