Date: Tue, 5 Jun 2007 15:39:05 -0700 (PDT) From: David Rientjes <rientjes@...gle.com> To: Andrew Morton <akpm@...ux-foundation.org> cc: Andi Kleen <ak@...e.de>, Christoph Lameter <clameter@...r.sgi.com>, Paul Jackson <pj@....com>, linux-kernel@...r.kernel.org Subject: [patch] cpusets: do not allow TIF_MEMDIE tasks to allocate globally Reverts git commit c596d9f320aaf30d28c1d793ff3a976dee1db8f5. OOM-killed tasks, marked as TIF_MEMDIE, should not be able to access memory outside its cpuset because it could potentially cause other exclusive cpusets to OOM themselves.
