Revision ff513ace9b772e75e337f8e058cc7f12816843fe authored by Ilya Dryomov on 03 February 2014, 11:56:33 UTC, committed by Sage Weil on 07 February 2014, 18:45:53 UTC
Handling redirect replies requires both map_sem and request_mutex.
Taking map_sem unconditionally near the top of handle_reply() avoids
possible race conditions that arise from releasing request_mutex to be
able to acquire map_sem in redirect reply case.  (Lock ordering is:
map_sem, request_mutex, crush_mutex.)
