Subject: [Patch v4 08/22] CIFS: SMBD: Upper layer reconnects to SMBDirect session
Date: Sun, 1 Oct 2017 19:30:16 -0700 [thread overview]
Message-ID: <20171002023030.3582-9-longli@exchange.microsoft.com> (raw)
In-Reply-To: <20171002023030.3582-1-longli@exchange.microsoft.com>
From: Long Li <longli@microsoft.com>
Do a reconnect on SMBDirect when it is used as the connection. Reconnect can
happen for many reasons and it's mostly the decision of upper layer SMB2.
