This patch adds additional punch hole tests to 252
that were used to test ext4 punch hole. The _test_generic_punch
routine has been modified to accept two new flags:
-k To keep the test file between tests.
This will test the handling of existing holes
-d To not sync the file between tests.
This will test the handling of delayed extents
Four new corner cases have also been added to the routine:
14. data -> hole @ EOF
15. data -> hole @ 0
16. data -> cache cold ->hole
17. data -> hole in single block file

Hi all,
I had some questions about test 12. The output for this test is:
12. unwritten -> data -> unwritten
0: [0..7]: unwritten
1: [8..31]: hole
2: [32..39]: unwritten
But ext4 gets data extents here instead of unwritten extents (on the
first test with the fsync flag on). I did some investigating and it
looks like the fsync command causes the extents to be written out before
the punch hole operation even starts. So it makes sense to me that it
should end up with data extents. Can someone explain why the golden
output has unwritten extents here? Thx!
