Hi All I have a question about the cn_test coming under Documentation/connector. From the code, cn_test_callback() is registered and a timer handler will call cn_netlink_send() every second. I compiled the code under FC5 and insmod the module. I also revised the code a bit to observe the return value of cn_netlink_send(). Unfortunately, the return value is always -ESRCH which http://lxr.linux.no/source/drivers/connector/connector.c?v=2.6.18#L102 show no listeners. But I thought cn_test_callback() is the listener?
