Subject: [PATCH v3 5/7] CIFS: set signing flag in SMB2+ TreeConnect if needed
Date: Tue, 28 Feb 2017 19:40:32 +0100	[thread overview]
Message-ID: <20170228184034.18771-6-aaptel@suse.com> (raw)
In-Reply-To: <20170228184034.18771-1-aaptel-IBi9RG/b67k@public.gmane.org>

cifs_enable_signing() already sets server->sign according to what the
server requires/offers and what mount options allows/forbids, so use
that.

this is required for IPC tcon that connects to signing-required servers.
