[0/2] btrfs/072:

Message

Running btrfs/072 on a zoned null_blk device fails with a mismatch of the
number of extents. That mismatch happens because the max size of extent is
limited by not only BTRFS_MAX_UNCOMPRESSED, but also zone_append_max_bytes
on the zoned mode.

Fix the issue by calculating the expected number of extents instead of
hard-coding it in the output file.

Also, use _fixed_by_kernel_commit to rewrite the fixing commit indication
in the comment.

  btrfs/072: support smaller extent size limit

Oops, I forgot to write the subject except the test case number. And, even
that test case number is wrong... I'll send v2 with proper subject lines.
