>From 0e99ae8cf891015105f01065e2977ea6cc737ff8 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Mon, 17 Dec 2012 11:03:42 +0100 Subject: [PATCH 1/2] ocfs2: Wait for page writeback to provide stable pages 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().
