I think we should drop the patch "[PATCH 6.1 012/208] selftests/vm: remove
__USE_GNU in hugetlb-madvise.c" from this merge.

That patch fixes commit 62f33fa22800 ("selftests/vm: use memfd for
hugetlb-madvise test"), but that's only in 6.2-rc1 and it's not in 6.1.

I don't really know why it got picked for 6.1 stable backport, because the
original patch doesn't contain "CC: stable".

Thanks,
