Thanks, Stephen! Now the patch has been in char-misc's char-misc-linus branch, so IMO we may as well leave it as is (considering the code here is unlikely to be frqeuencly changed), and we have a smaller patch this way. :-) But, yes, I agree with you that generally we should make a common function to avoid duplicate code.
