Let's return early for hugetlb, which really only relies on the compound mapcount so far and does not support PageDoubleMap() yet. Use the chance
It is too early to say if hugetlb double mapping will use PageDoubleMap(). I do not think (hope) it will be necessary. So, I think you can drop mention of it here.
Desires have most certainly been expressed from a couple of parties -- to PTE map huge pages :) Hopefully we'll find a way to avoid PageDoubleMap, I agree.
Dropping the comment!
to cleanup the file-THP case to make it easier to grasp. While at it, use head_compound_mapcount().
This is a preparation for further changes.
