Subject: [Patch v3 06/19] CIFS: SMBD: Reconnect to SMBDirect session
Date: Tue, 29 Aug 2017 12:29:02 -0700	[thread overview]
Message-ID: <20170829192915.26251-7-longli@exchange.microsoft.com> (raw)
In-Reply-To: <20170829192915.26251-1-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 not
SMBDirect.
