Thanks.  The major issues I noticed when doing a quick scan of the
patches you've already mentioned here.  I'll try to take a closer look
in the next week or so when I have time.

One random question --- in the huge=always approach, how much
additional work would be needed to support file systems with a 64k
block size on a system with 4k pages?
