From 9d6fcb081a4770c3772c51c59c7251c22716d7bb Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Thu, 12 May 2011 15:48:16 -0700 Subject: [PATCH] ceph: check return value for start_request in writepages Since we pass the nofail arg, we should never get an error; BUG if we do. (And fix the function to not return an error if __map_request fails.)
