So the issue is that mac80211 cannot remove the debugfs entries the driver creates here, because it only removes the interface debugfs when the interface is destroyed, not when it is taken down. The driver, OTOH, gets add/remove when the interface goes up/down. Would anyone complain if we just document that and require that the driver actually remove its entries when the new remove_interface_debugfs callback is called? That'd be a bit unlike other debugfs dirs where everything just gets cleaned up in mac80211. johannes -- 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
