Subject: [Patch v8 05/16] CIFS: SMBD: Upper layer destroys SMB Direct session on shutdown or umount
Date: Wed, 22 Nov 2017 17:38:38 -0700 [thread overview]
Message-ID: <20171123003849.17093-6-longli@exchange.microsoft.com> (raw)
In-Reply-To: <20171123003849.17093-1-longli@exchange.microsoft.com>
From: Long Li <longli@microsoft.com>
When upper layer wants to umount, make it call shutdown on transport when
SMB Direct is used.
