From d0265de7c358d71a494dcd1ee28206b32754bb0f Mon Sep 17 00:00:00 2001 From: Josh Durgin Date: Mon, 7 Apr 2014 16:54:10 -0700 Subject: [PATCH] rbd: tolerate -ENOENT for discard operations Discard may try to delete an object from a non-layered image that does not exist. If this occurs, the image already has no data in that range, so change the result to success.
