[PATCH v3 14/14] name-rev: cleanup name_ref()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Earlier patches in this series moved a couple of conditions from the
recursive name_rev() function into its caller name_ref(), for no other
reason than to make eliminating the recursion a bit easier to follow.

Since the previous patch name_rev() is not recursive anymore, so let's
move all those conditions back into name_rev().
