From e1518c7c0a67a75727f7285780dbef0ca7121cc9 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Thu, 13 May 2010 11:19:06 -0700 Subject: ceph: clean up mds reply, error handling We would occasionally BUG out in the reply handler because r_reply was nonzero, due to a race with ceph_mdsc_do_request temporarily setting r_reply to an ERR_PTR value. This is unnecessary, messy, and also wrong in the EIO case. Clean up by consistently using r_err for errors and r_reply for messages. Also fix the abort logic to trigger consistently for all errors that return to the caller early (e.g., EIO from timeout case). If an abort races with a reply, use the result from the reply. Also fix locking for r_err, r_reply update in the reply handler.
