Hang on. /dev/kmsg was implemented using a mailslot and it was never accessible via the syslog(3) interface. The code you removed has nothing to do with /dev/kmsg. What the code does is to check if we have a listener on the /dev/msg UDP socket, otherwise log data may get lost or, IIRC, the syslog call may even hang. So removing this code sounds like a bad idea. Can you please explain *why* removing this code helps and what happens if syslogd is not running after removing the code?
