Given that we have run into issues so much with it that's proably
the better idea.
To fix the originally reported issue with the missing file size updates
in XFS we plan to simply log all filesize changes in XFS. Currently I
had this in the 3.3 queue, but in the worst case we might have to move
this forward to 3.2.

Please do so. I'm really looking forward to see the I/O-less
balance_dirty_pages in ASAP.
