ceph: fix iput race when queueing inode work If we queue a work item that calls iput(), make sure we ihold() before attempting to queue work. Otherwise our queued work might miraculously run before we notice the queue_work() succeeded and call ihold(), allowing the inode to be destroyed. That is, instead of if (queue_work(...)) ihold(); we need to do ihold(); if (!queue_work(...)) iput(); Reported-by: Amon Ott <a.ott@m-privacy.de> Signed-off-by: Sage Weil <sage@newdream.net>
