Subject: [PATCH 0/5] {ioctl_}userfaultfd.2: initial updates for 4.11

Hello Michael,

These patches are some kind of brief highlights of the changes to the
userfaultfd pages.
The changes to userfaultfd functionality are also described at update to
Documentation/vm/userfaultfd.txt [1].

In general, there were three major additions:
* hugetlbfs support
* shmem support
* non-page fault events

I think we should add some details about using userfaultfd with different
memory types, describe meaning of each feature bits and add some text about
the new events.

I haven't updated 'struct uffd_msg' yet, and I hesitate whether it's
description belongs to userfaultfd.2 or ioctl_userfaultfd.2

As for the userfaultfd.7 we've discussed earlier, I believe it would
repeat Documentation/vm/userfaultfd.txt in way, so I'm not really sure it
is required.

Sincerely yours,
Mike.
