Subject: [PATCH 5/6] ocfs2: Wait for page writeback to provide stable pages
Date: Mon, 14 Jan 2013 21:43:13 -0800 [thread overview]
Message-ID: <20130115054313.1563.70148.stgit@blackbox.djwong.org> (raw)
In-Reply-To: <20130115054235.1563.12967.stgit@blackbox.djwong.org>
When stable pages are required, we have to wait if the page is just
going to disk and we want to modify it. Add proper callback to
ocfs2_grab_pages_for_write().
