Subject: [Patch v2 07/15] CIFS: When sending data on socket, pass the correct page offset
Date: Wed, 30 May 2018 12:47:59 -0700 [thread overview]
Message-ID: <20180530194807.31657-8-longli@linuxonhyperv.com> (raw)
In-Reply-To: <20180530194807.31657-1-longli@linuxonhyperv.com>
From: Long Li <longli@microsoft.com>
It's possible that the offset is non-zero in the page to send, change the
function to pass this offset to socket.
