We usually add new tests, so existing test wont start failing
for unpatched kernels.

I could just as well write:

Since xfs_io does not support xattrs, we need to add xattrs support to xfs_io

but I won't be the one to insist on that.

What you did is you cloned attr_replace_test.c with the tiniest change
and did not even bother to mention that.

Please add -T flag support to attr_replace_test.c (following xfs_io -T)
instead of cloning the helper and use that in your new test.

Thanks,
Amir.
