So, I will create a 2nd wait queue in random.c for uninterruptible waits, 
change the get_blocking_random_bytes back to void and use wait_event to wait 
for the initialization.

Hold your horses.  You don't need a second queue, you just need to
change wake_up_interruptible to wake_up.

Hmm, in fact shouldn't this be wake_up_all? Otherwise what are the
other getrandom(2) callers going to do? Ted?

Yes, this should definitely be wake_up_all()
