/dev/kmsg is used to read/write to the kernel printk ring buffer, which is
read by dmesg or klogd utilities.

/dev/log is an UNIX sockt created by sysogd, when invoked, and listens for
any incoming messgaes on this. The messages are written into it by the
system's syslog functionality.

Syslogd can listen on additional sockets provided through __ -a__ option.
