Need for put_user/get_user
I've read all kinds of things from the address may be in the wrong segment (but the segments are now flat).
When I read the code it appears both the C and assembly for x86 just check the address range.
So the question is assuming I know that the user has passed a valid address, is why use the function?
I have run tests which work perfectly well without using this. So is there some corner case I'm not aware of?
