[GFS2] Allow page migration for writeback and ordered pages
To improve performance on NUMA, we use the VM's standard page migration for writeback and ordered pages. Probably we could also do the same for journaled data, but that would need a careful audit of the code, so will be the subject of a later patch. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
