Yes, that is all expected behavior if you don't run as root and your user
doesn't have the necessary capabilities added - similar to other tests
with privileged operations.

Great, thanks. Perhaps some explicit capabilities tests and clearer error
messages would make sense as a follow-on patch.

Thanks for working with me to get these into the kernel, I think it will
improve futex test exposure and hopefully encourage people to write more
tests to fill some of the gaps.
