What is the proper or best practice method for the kernel to notify a user level process (or processes) of an event. This event may possibly have data. The processes may or may not exist. The event is generated by some arbitrary kernel event (a counter, a call being made, etc.) Typically I have seen this done as file I/O via a device. syslogd is a program that fits this description. A special device '/dev/klog' was provided for it. What is the best practice these days? Please reply to me directly, I will summarize the results to the list.
