3.5.7u1 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Sage Weil <[email protected]> commit 85effe183dd45854d1ad1a370b88cddb403c4c91 upstream. 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.
