Is that a bug? It is a bug. The only legal nesting is base --> BH --> IRQ locking. > Also, if you're going to treat IRQs being enabled as a bug, there's no > point in disabling them right afterwards, is there? It's treating IRQs being "disabled" as a bug. It expects them to be enabled, always. > If you're going to reject this patch, I'll post one that adds the > warning to local_bh_enable_ip() to allow detecting this for everybody > and not just those poor people running UP/NO-PREEMPT :) That might be useful :) -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
