They are debug warnings, not oopses.

airo_get_stats is called under the read_lock(&dev_base_lock); which was taken in dev_get_info. So it may not call sleeping functions (ie: down_interruptible()).
It would appear that no netdevice->get_stats() method is allowed to sleep, which seems pretty dumb, IMVHO. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
