I just did it that way to match the flag clearing for normal pages. I can
move it into dequeue if you think it's worthwhile but in the worst case it
just adds a clear_bit call, so I doubt it's measurable.

I do not have a strong opinion on that but the flags come in cleared when
they are freshly allocated (gather_surplus_pages) so then it would be
more appropriate in free_huge_page when enqueue_huge_page is called.

Makes sense, I'll move the call into free_huge_page.

Cheers,
