Useful if one need a prefix over module messages. I use it in tty c/r, thus having something like | TTY: master 0x31 index 2 fd 6 pid 5079 (create 1) | TTY: `- slave 0x5c index 2 fd 255 pid 5080 (create 0 send 0) | TTY: standalone slave 0x2e index 1 fd 3 pid 5079 (create 1) in log. Which helps filtering messages. Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
