I think a test of MMAP CoW is also needed for these kind of testsets.  So,
add MMAP CoW for each case.

Shiyang Ruan (5):
  generic/xxx: Add MMAP CoW test for 'regular' case
  generic/xxx: Add MMAP CoW test for 'unwritten' case
  generic/xxx: Add MMAP CoW test for 'hole' case
  generic/xxx: Add MMAP CoW test for 'delalloc' case
  generic/xxx: Add MMAP CoW test for 'all' case

Thanks for all these tests!

You could remove the 'xxx' part from patch summary, and for new tests
you don't have to write the specific test seq number in summary,
something like below is fine

   generic: add mmap CoW test for 'regular' case

As test seq number will always change on commit, there's no need to keep
such a place holder.

Thanks,
Eryu
