Linus, Al, Eric, This small series implement the exact-match comparison ahead of the case-insensitive comparison as suggested by Linus. The first patch only exposes dentry_string_cmp in a header file so we can use it instead of memcmp and the second actually do the optimization in the case-insensitive comparison code.
