Subject: [PATCH] SUNRPC: Fix possible autodisconnect during connect due to stale last_used
Date:   Wed, 26 Jun 2019 15:50:06 -0400
Message-Id: <1561578606-24602-1-git-send-email-dwysocha@redhat.com>
Sender: linux-nfs-owner@vger.kernel.org
Precedence: bulk

When a connection is successful ensure last_used is updated before calling
xprt_schedule_autodisconnect inside xprt_unlock_connect.  This avoids a
possible xprt_autoclose firing immediately after connect sequence due to
an old value of last_used given to mod_timer in xprt_schedule_autodisconnect.
