From: Trond Myklebust <trond.mykleb...@primarydata.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 485f2251782f7c44299c491d4676a8a01428d191 upstream.
When the server is unavailable due to a networking error, etc, we want
the RPC client to respect the timeout delays when attempting to reconnect.
Reported-by: Neil Brown <ne...@suse.de>
Fixes: 561ec1603171 (SUNRPC: call_connect_status should recheck bind..)
