Porting Notes:
- Most of 7252 was already picked up during ABD work.  This
  commit represents the gap from the final commit to openzfs.
- Fixed split_large_blocks check in do_dump()
- An alternate version of the write_compressible() function was
  implemented for Linux which does not depend on fio.  The behavior
  of fio differs significantly based on the exact version.
- mkholes was replaced with truncate for Linux.
