v2:
- Added R-bs for Phil
- Move open_mode into uffd_detect_open_mode() [Phil]
- Document uffd_open() in the header file [Phil]
- [Discussed with Daniel/Michal, decided to leave fd support for later]
The new /dev/userfaultfd handle is superior to the system call with a
better permission control and also works for a restricted seccomp
environment.
The new device was only introduced in v6.1 so we need a header update.
Please have a look, thanks.
