Subject: [Patch v8 03/16] CIFS: SMBD: Upper layer reconnects to SMB Direct session
Date: Wed, 22 Nov 2017 17:38:36 -0700	[thread overview]
Message-ID: <20171123003849.17093-4-longli@exchange.microsoft.com> (raw)
In-Reply-To: <20171123003849.17093-1-longli-Lp/cVzEoVyZiJJESP9tAQJZ3qXmFLfmx@public.gmane.org>

From: Long Li <longli-0li6OtcxBFHby3iVrkZq2A@public.gmane.org>

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.
