Is there any particular reason the upcalled program has to be run as root?
Could the kernel not run it as something else - perhaps the caller's UID,GID
or even something anonymous?

Also, call_sbin_request_key() could be given a parameter to call something
other than /sbin/request-key, and key_type::request_key could be used.
