libceph: take map_sem for read in handle_reply() 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.) Signed-off-by: Ilya Dryomov <ilya.dryomov@inktank.com> Reviewed-by: Sage Weil <sage@inktank.com>
