I've been snowed under trying to get several different things done
all at the same time, so this has slipped. I'm trying to get back to
it early next week. The nr_to_pages fix is badly needed, as that
causes severe fragmentation in XFS for the exact workloads it fixes
the severe fragmentation in ext4....

Cheers,

Dave.
