[RFC PATCH] [TCP]: Fix lost_retrans loop vs fastpath problems

2007-10-09 Thread Ilpo Järvinen
Detection implemented with lost_retrans must work also when fastpath is taken, yet most of the queue is skipped including (very likely) those retransmitted skb's we're interested in. This problem appeared when the hints got added, which removed a need to always walk over the whole write queue head.
