Can a driver give root privileges to a process?

The sys_mlock() call can only be called by a process with root privileges. I'm working on a library that calls a driver on behalf of a non-root process to perform some stuff, and one of these things the driver does is call sys_mlock().

Would it be possible for the driver to give root privileges to the process, at least temporarily, so that the library can call sys_mlock() instead? Obviously, there would be security issues with this, but let's ignore that for the moment.
