There's a known bug fix 392c6de98af1 ("xfs: sanitize sb_inopblock in
xfs_mount_validate_sb"). So try to corrupt the sb_inopblock of xfs,
to cover this bug.

V2 does below changes:
1) Add _fixed_by_kernel_commit ...
2) Repair and check the xfs at the test end
Thanks,
Zorro

not be necessary since iirc 'write' has been in db for a long time now.
Either way, this test looks ok to me so
