There're two features missing in current manpage, namely: (1) Userfaultfd Thread-ID feature (2) Userfaultfd write protect mode There's also a 3rd one which was just contributed from Axel - Axel, I think it would be great if you can add that part too, probably after the whole hugetlbfs/shmem minor mode reaches the linux master branch. Please review, thanks.
