Merge from irix/cxfs-f to irix/irix6.5f
Merge of cxfs-f:irix:15011b created by lord on 05/11/99
  Merge from irix/cxfs to irix/cxfs-f
  Merge of cxfs:irix:13423a created by lord on 04/19/99
  CXFS infrastructure checkin
  Merge of cxfs:irix:14965a created by lord on 05/10/99
  This adds the hooks in the infrastructure for the xfs
  defragmenter to function correctly on a cxfs exported
  filesystem.
  Add prototypes for callouts from the defragmenter
  extent swapping code into cxfs.

Merge of cxfs-f:irix:15285a created by lord on 05/12/99
  Clean up XFS code so that cxfs can use more of it for
  unwritten extent conversion.
  This is part 1 of 2 so that it can be merged into the
  'pre-merge' tree.
  Add prototype for cxfs_strat_complete_buf
