Let me clarify:
1) 9d9b1ee0b2d1 tcp: fix TCP_USER_TIMEOUT with zero window
fixes the bug and makes it work.
2) The current patch makes the TCP_USER_TIMEOUT accurate for 0-window probes. It's independent.
With 1) and 2), the known issues with TCP_USER_TIMEOUT for 0-window probes would be resolved.
Thanks. -- Enke
