Subject: [PATCH 116/270] libceph: set peer name on con_open, not init
3.5.7u1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Sage Weil <sage@...tank.com>
commit b7a9e5dd40f17a48a72f249b8bbc989b63bae5fd upstream.
The peer name may change on each open attempt, even when the connection is
reused.
