Message-ID: <20110527135205.GF4067@tiehlicka.suse.cz> Date: Fri, 27 May 2011 15:52:05 +0200 From: Michal Hocko <mhocko@...e.cz> To: Andrew Morton <akpm@...ux-foundation.org> Cc: Mel Gorman <mgorman@...e.de>, LKML <linux-kernel@...r.kernel.org> Subject: [PATCH trivial] Use BUILD_BUG_ON for VM_STACK_FLAGS & VM_STACK_INCOMPLETE_SETUP a8bef8ff has introduced BUG_ON to force that VM_STACK_FLAGS and VM_STACK_INCOMPLETE_SETUP do not overlap. The check is compile time so BUILD_BUG_ON is more appropriate.
