The API is trivial, and so is the implementation.  Linux priorities are
exposed to the userspace, so nobody should claim that software aware of
Linux priorities is a derived work of the kernel.

The complementary function set_user_nice() is available to non-GPL
modules.  If the module can set the priority, it should be able to read
it back.
