Hmm, one other sk_forward_alloc corruption I guess...

I fixed one corruption but this is only about UDP sockets used by SUNRPC,
while your traces seems to point a TCP problem.


This is a note to let you know that we have just queued up the patch titled

Subject: net: fix sk_forward_alloc corruption

to the 2.6.31-stable tree. Its filename is

net-fix-sk_forward_alloc-corruption.patch
