Can a driver give root privileges to a process?

[Timur Tabi <timur.tabi@xxxxxxxxxxx>]

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.
