Subject: [Patch v6 12/22] CIFS: SMBD: Upper layer destroys SMB Direct session on shutdown or umount
Date: Sat, 4 Nov 2017 22:43:54 -0700 [thread overview]
Message-ID: <20171105054404.23886-13-longli@exchange.microsoft.com> (raw)
In-Reply-To: <20171105054404.23886-1-longli-Lp/cVzEoVyZiJJESP9tAQJZ3qXmFLfmx@public.gmane.org>
From: Long Li <longli-0li6OtcxBFHby3iVrkZq2A@public.gmane.org>
When upper layer wants to umount, make it call shutdown on transport when
SMB Direct is used.
