Subject: [PATCH 2/6] xfs: ioends require logically contiguous file offsets
Date: Mon, 7 Mar 2016 08:49:46 +1100 [thread overview]
Message-ID: <1457300990-18300-3-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1457300990-18300-1-git-send-email-david@fromorbit.com>
From: "Darrick J. Wong" <darrick.wong@oracle.com>
We need to create a new ioend if the current writepage call isn't
logically contiguous with the range contained in the previous ioend.
Hopefully writepage gets called in order of increasing file offset.
