| |
3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Trond Myklebust <trond.myklebust@primarydata.com>
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.
