Date: Fri, 9 May 2008 12:41:17 +0200 From: Christoph Hellwig <hch@....de> To: starvik@...s.com, jesper.nilsson@...s.com, torvalds@...l.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH] cris: kill sys_pipe implementation The cris implementation of sys_pipe only differs from the generic one by taking the BKL before calling do_pipe which isn't not nessecary. Just kill the cris implementation and use the generic one.
