Tue 11 Oct 2011 07:53:36 PM UTC, comment #2: After coding 2 unit test cases to check unsent/unacked list sorting on fast/rto rexmit and checking the code (segments are only added to unacked in tcp_output), I don't think we have a problem with unsorted lists. We did however have such a problem until 1.3.0, so maybe he used an old version?
