I didn't see anywhere (in this patch) call `_require_xfs_io_command parent`.
Shouldn't we make sure the "parent" feature is support by userspace and
kernel both?

I think we'd better to check if current fs userspace and kernel support
"parent" feature. If it's supported, then we should report failure if
mkfs fails. Or we should skip the test before real testing start. (same
below)

Thanks, by the way, can you separate this patch to 3~4 patches as a patchset,
it's a little hard for me to go through this long patch and page up and down
to review sometimes :)

I remembered last time you backup the value of the xfs/debug/larp, then restore
it in cleanup, refer to xfs/018 (it might be recommended by Dave?).

I'm wondering if old kernel can mount xfs with "parent=1"? If not, we need
a _require_xfs_parent. For example we have below 3 function in common/xfs:
_require_xfs_mkfs_crc : check if current mkfs.xfs support crc=1 option
_require_xfs_crc : check if current kernel can mount a xfs with crc=1
_require_scratch_xfs_crc : check if current SCRATCH_DEV is crc enabled
As the parent feature isn't big as crc feature, so I think you can refer
to _require_xfs_sparse_inodes or _require_xfs_nrext64, check mkfs and kernel
support parent feature in one function. Then you can use:
_require_xfs_parent # check mkfs and kernel/mount support parent feature
_require_xfs_io_command parent # check if xfs_io support parent command
at the beginning of each cases.

I think it wouldnt be a bad idea to print out what the name and length
are vs what they were expected to be. Since that will only print
during a test fail anyway, I think that's clearer than having to go
pour through the diff output.

I think it does now. We went through a couple different
implementations of larp knobs and at some point it really wasn't
reasonable to continue pushing out all the resulting changes that would
ripple through not only usr space but all the test cases as well. I
think thats setting down now, so I think it's ok for this line to come
out.

Yes, this is similar to the larp replay tests except we ensure the
