Message-Id: <a9c04c2664148dae99208fdd69ee20f6a4b68120.1352410985.git.ecashin@coraid.com> Date: Thu, 8 Nov 2012 19:17:15 -0500 From: Ed Cashin <ecashin@...aid.com> To: Andrew Morton <akpm@...ux-foundation.org> Cc: linux-kernel@...r.kernel.org, ecashin@...aid.com, axboe@...nel.dk Subject: [PATCH 1/8] aoe: avoid running request handler on plugged queue Calling the request handler directly on a plugged queue defeats the performance improvements provided by the plugging mechanism. Use the __blk_run_queue function instead of calling the request handler directly, so that we don't interfere with the block layer's ability to plug the queue.
