When new return values appear, the function should be renamed to help the patch author and reviewers remember to check all callers. That is, from the point of view of maintainability, there is no distinction between "if (read_packets_until_... < 0)" and "if (read_packets_until_...)" and either form is fine. My comment was just to say the "< 0" forced me to pause a moment and check out the implementation. This is basically a stylistic thing and if you prefer to keep the "< 0", that's fine with me. > If > an implementation is producing bogus packet lines and expecting us not > to complain, it really needs to be fixed. Agreed completely. Thanks again for the patch.
