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

[Mike Rapoport <rppt@linux.vnet.ibm.com>]

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.
