Tom Herbert	cd6e111bf5	kcm: Add statistics and proc interfaces ... This patch adds various counters for KCM. These include counters for messages and bytes received or sent, as well as counters for number of attached/unattached TCP sockets and other error or edge events. The statistics are exposed via a proc interface. /proc/net/kcm provides statistics per KCM socket and per psock (attached TCP sockets). /proc/net/kcm_stats provides aggregate statistics.

Tom Herbert	ab7ac4eb98	kcm: Kernel Connection Multiplexor module ... This module implements the Kernel Connection Multiplexor. Kernel Connection Multiplexor (KCM) is a facility that provides a message based interface over TCP for generic application protocols. With KCM an application can efficiently send and receive application protocol messages over TCP using datagram sockets.
