The locking is wrong. At the moment the entire kernel assumes that a
process uid is not changed by anyone else. After you've implemented uid
locking/refcounting for tasks you can add the syscall but until then its
not a good idea. I don't think its a good idea anyway - selinux can do
far more useful things.
