That would be correct. The old tty driver layer used to call ->write from both kernel and user contexts according to a flag. Drivers then all ended up with the same code copying it into a tmp buffer and using a locking semaphore. Linus took out that code and arranged that ->write always got a kernel buffer so the remainders should indeed go.
