I am quite surprised that nobody else noticed this before. Linus has a G5. Hackers hate printing in general, maybe. We do not use BKL anymore, because one of code paths had a sleeping call, so we had to use a semaphore. I am sure it's safe to use unlocked_ioctl. The new ioctls return long and retval is int. It looks completely fine to me. We never want these extra bits, and the sign extension ought to work right.
