Hi Dave,

Sacktag fastpath_cnt_hint seems to be very tricky to get right...
I suppose this one fixes Cedric's case. I cannot say for sure    
until there is something more definite indication of
tcp_retrans_try_collapse origin than what the simple late WARN_ON
gave for us. ...Especially since it's non-trivial to have skb
hint "correctly" positioned in the write_queue while still ending
up calling that function. However, considering how difficult it
seems to be for Cedric to reproduce, it might well be this one.

In addition, I noticed another reset which wasn't previously   
converted to WARN_ON, so doing that now. Boot + simple xfer
tested. Please apply to net-2.6.24.
