3.5.7u1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Sage Weil <s...@inktank.com>
commit 3a140a0d5c4b9e35373b016e41dfc85f1e526bdb upstream.
We need to set error_msg to something useful before calling ceph_fault();
do so here for try_{read,write}(). This is more informative than
libceph: osd0 192.168.106.220:6801 (null)
