+         If you say Y here, a user level program will be able to map
+         file names to handle and then later use the handle for
+         different file system operations. This is useful in implementing
+         userspace file servers, which now track files using handles instead
+         of names. The handle would remain the same even if file names
+         get renamed. Enables open_by_handle_at(2) and name_to_handle_at(2)
+         syscalls.
