Subject: libceph: reset connection retry on successfully negotiation
From: Sage Weil <[email protected]>
(cherry picked from commit 85effe183dd45854d1ad1a370b88cddb403c4c91)
We exponentially back off when we encounter connection errors. If several
errors accumulate, we will eventually wait ages before even trying to
reconnect.
Fix this by resetting the backoff counter after a successful negotiation/
connection with the remote node. Fixes ceph issue #2802.
