- Add support for setting the filesystem's maximum size and maximum inode
  count on the mount command line.

  This is needed because the system admin can now set the ownership of teh
  fs to non-root users.  We don't want those users to be able to use all of
  the hugepage pool.

- Prroperly update the inode creation/modification time.

- Set the blocksize to HPAGE_SIZE (instead of PAGE_CACHE_SIZE).

- Update Documentation/vm/hugetlbpage.txt.
