Hello

As a part of investigation into issue affecting mmap with MAP_HUGETLB [1], I was thinking if huge pages should have a dedicated mediation class and be handled similarly to how mqueue was recently added.

In the kernel, `aa_file_perm` function could special case hugetlbfs so that mmap would not end up using odd (possibly disconnected) paths for accessing it.

I'd be happy to pick up this work if there is consensus on the general direction. I would need some help with reviews and guidance along the way.

Best regards
ZK
