Subject: [Patch v5 08/21] CIFS: SMBD: Upper layer reconnects to SMB Direct session
Date: Wed, 18 Oct 2017 16:09:07 -0700 [thread overview]
Message-ID: <20171018230920.21042-9-longli@exchange.microsoft.com> (raw)
In-Reply-To: <20171018230920.21042-1-longli@exchange.microsoft.com>
From: Long Li <longli@microsoft.com>
Do a reconnect on SMB Direct when it is used as the connection. Reconnect can
happen for many reasons and it's mostly the decision of SMB2 upper layer.
