Message-Id: <1321732460-14155-3-git-send-email-aarcange@redhat.com> Date: Sat, 19 Nov 2011 20:54:14 +0100 From: Andrea Arcangeli <aarcange@...hat.com> To: linux-mm@...ck.org Cc: Mel Gorman <mgorman@...e.de>, Minchan Kim <minchan.kim@...il.com>, Jan Kara <jack@...e.cz>, Andy Isaacson <adi@...apodia.org>, Johannes Weiner <jweiner@...hat.com>, linux-kernel@...r.kernel.org Subject: [PATCH 2/8] mm: compaction: Use synchronous compaction for /proc/sys/vm/compact_memory From: Mel Gorman <mgorman@...e.de> When asynchronous compaction was introduced, the /proc/sys/vm/compact_memory handler should have been updated to always use synchronous compaction. This did not happen so this patch addresses it. The assumption is if a user writes to /proc/sys/vm/compact_memory, they are willing for that process to stall.
