With current linus git (HEAD 8ae516aa), I got following kernel message.
This is slightly different from what I had reported recently (14th Nov).

I guess the prolem is that the STATS _BH functions are to be used if they
are executed in bottom half and maybe people expect it to protect against
bottom half. We seem to have some more of this problems in udp_sendmsg
(this trace) and ping_sendmsg, maybe in tcp, too. The non-_BH functions
actually disable bh.

I'll check for more prolems and will post a patch.

Thanks for reporting,
