| |
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.
This is the re-based set on the recent userfaultfd branch, two major changes are:
* No need in separate API version, the uffd_msg introduced in the current code and UFFD_API ioctl are enough for the needed extentions * Two events added -- for mremap() and madvise() MADV_DONTNEED
More details about the particular events are in patches 3 trough 4. Comments and suggestion are warmly welcome :)
The v1 discussion thread is here: https://lkml.org/lkml/2015/3/18/729
Thanks, Pavel
