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, Hannes
