I'm looking at trying to possibly merge the 32-bit and 64-bit versions of the x86 uaccess.h implementation, but first this needs to be cleaned up. For example, the 32-bit version of "__copy_to_user_inatomic()" is mostly the special cases for the constant size, and it's actually never relevant. Every user except for one aren't actually using a constant size anyway, and the one user that uses it is better off just using __put_user() instead. So get rid of the unnecessary complexity. [ The same cleanup should likely happen to __copy_from_user_inatomic() as well, but that one has a lot more users that I need to take a look at first ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
