Subject: [PATCH 07/27] SUNRPC: Move reset of TCP state variables into the reconnect code
Date: Mon,  3 Sep 2018 11:29:16 -0400	[thread overview]
Message-ID: <20180903152936.24325-8-trond.myklebust@hammerspace.com> (raw)
In-Reply-To: <20180903152936.24325-7-trond.myklebust@hammerspace.com>

Rather than resetting state variables in socket state_change() callback,
do it in the sunrpc TCP connect function itself.
