Subject: [PATCH 25/27] Re-sort GFP flags and fix whitespace alignment for easier reading.
Date: Mon, 16 Mar 2009 17:53:39 +0000	[thread overview]
Message-ID: <1237226020-14057-26-git-send-email-mel@csn.ul.ie> (raw)
In-Reply-To: <1237226020-14057-1-git-send-email-mel@csn.ul.ie>

Resort the GFP flags after __GFP_MOVABLE got redefined so how the bits
are used are a bit cleared.

From: Peter Zijlstra <a.p.zijlstra@chello.nl>
