[PATCH 0/5] userfaultfd: extension for non cooperative uffd usage

[Mike Rapoport]

Hi,

This set is to address the issues that appear in userfaultfd usage
scenarios when the task monitoring the uffd and the mm-owner do not 
cooperate to each other on VM changes such as remaps, madvises and 
fork()-s.

The pacthes are essentially the same as in the prevoious respin (1),
they've just been rebased on the current tree.

  uffd: Split the find_userfault() routine
  uffd: Add ability to report non-PF events from uffd descriptor
  uffd: Add fork() event
  uffd: Add mremap() event
  uffd: Add madvise() event for MADV_DONTNEED request
