Subject: [PATCH v2 03/22] memcg: use vm_swappiness from current memcg
Date: Mon, 20 Feb 2012 21:22:46 +0400 [thread overview]
Message-ID: <20120220172246.22196.82590.stgit@zurg> (raw)
In-Reply-To: <20120220171138.22196.65847.stgit@zurg>
At this point this is always the same cgroup, but it allows to drop one argument.
