Merge of 2.3.99pre2-xfs:slinx:63295a originally by nathans on 06/03/00
  move the xfsstats structure declaration here with other XFS types.

Merge of 2.3.99pre2-xfs:slinx:63304a originally by nathans on 06/03/00
  remove the xs_xfsd_bufs counter as this is no longer used.

 * Some types are conditional based on the selected configuration.
 * Set XFS_BIG_FILES=1 or 0 and XFS_BIG_FILESYSTEMS=1 or 0 depending
 * on the desired configuration.
 * XFS_BIG_FILES needs pgno_t to be 64 bits (64-bit kernels).
 * XFS_BIG_FILESYSTEMS needs daddr_t to be 64 bits (N32 and 64-bit kernels).
 *
 * Expect these to be set from klocaldefs, or from the machine-type
