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.
