Subject: [Patch v2 11/15] CIFS: Pass page offset for calculating signature
Date: Wed, 30 May 2018 12:48:03 -0700 [thread overview]
Message-ID: <20180530194807.31657-12-longli@linuxonhyperv.com> (raw)
In-Reply-To: <20180530194807.31657-1-longli@linuxonhyperv.com>
From: Long Li <longli@microsoft.com>
When calculating signature for the packet, it needs to read into the
correct page offset for the data.
