Subject[PATCH 3.12 108/122] SUNRPC: Ensure that call_connect times out correctly
Date
From: Trond Myklebust <trond.myklebust@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 <neilb@suse.de>
Fixes: 561ec1603171 (SUNRPC: call_connect_status should recheck bind..)
