Message-Id: <20100924181302.7d764e0d.kamezawa.hiroyu@jp.fujitsu.com> Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-linux-mm@kvack.org To: "linux-mm@kvack.org" Cc: "linux-kernel@vger.kernel.org" , "balbir@linux.vnet.ibm.com" , "nishimura@mxp.nes.nec.co.jp" , "akpm@linux-foundation.org" List-ID: This is a reviced series of use ID. Restart from RFC. [1/2] implementation of special ID lookup [2/2] use ID in mm/memcontrol.c People may say use css_lookup() and don't add a special routine but I can't believw css_lookup() can give us enough speed at every page LRU handling if the number of cgroup is big. I think this patch itself is enough simple... but I admit this will make mem_cgroup more complex. Hmm.
