I just noticed it in our CI reporting fails due to this change since at 
least linux-next 20210409. Suppose it came via 
https://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux-block.git/commit/?h=for-5.13/block&id=aaff5ebaa2694f283b7d07fdd55fb287ffc4f1e9

Wanted to ask before I adapt the test cases.

What does your CI do with it?

It would be kinda of sad to carry around this baggage, but if real
userspace is broken by the chance we'll have to do it.  I'm just not
entirely sure testcases qualify as real userspace yet.
