+Ummunotify relays MMU notifier events to userspace.  This is useful
+for libraries that need to track the memory mapping of applications;
+for example, MPI implementations using RDMA want to cache memory
+registrations for performance, but tracking all possible crazy cases
+such as when, say, the FORTRAN runtime frees memory is impossible
+without kernel help.
