> netpoll always played a little fast'n'lose with various locking rules. The current code is fine, it never reenters ->poll, because it maintains a "->poll_owner" which it checks in netpoll_send_skb() before trying to call back into ->poll. Every call to ->poll first sets ->poll_owner to the current cpu id. netpoll_send_skb() aborts and does a drop if ->poll_owner is set to the current smp_processor_id(). I sometimes feel like I'm the only person actually reading the sources and past threads on this topic before replying. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
