tcp collapse+splice bug still present in -stable

[Willy Tarreau]

David, Greg,

one of our customers was encountering frequent kernel panics up to
2.6.32.21 that were always related to splicing and tcp_collapse().
I found the precise BUG_ON() line but I've not forgotten it, something
about ->seq not being OK.

I found the following fix in 2.6.35 which looked to be related to the
same issue, and we could verify that it definitely solves it. Could we
please have it in other stable versions ?

Thanks in advance,
Willy
