Since 9f5afeae5152 ("tcp: use an RB tree for ooo receive queue")
applied, we no longer need to continue to search for the starting
point once we encounter FIN packet. Same reasoning for SYN packet
since commit 9d691539eea2d ("tcp: do not enqueue skb with SYN flag"),
that would help us with error message when actual receiving.

Very confusing changelog or patch.

What exact problem do you want to solve ?

That I thought as unnecessary search for the starting point. I am going to re-
read all to correct my misunderstanding.
Thank you.
