[PATCH 00/11] RFC: KBUS messaging subsystem

KBUS is a lightweight, Linux kernel mediated messaging system,
particularly intended for use in embedded environments.

It is meant to be simple to use and understand. It is designed to
provide predictable message delivery, deterministic message ordering,
and a guaranteed reply for each request. It is especially aimed at
situations where existing solutions, such as DBUS, cannot be used,
typically because of system constraints.

We have various customers using KBUS in real life, and believe it to
be useful. I had a showcase table for KBUS at the ELCE in Cambridge,
October last year, and there seemed to be interest.

The KBUS project home page is at http://kbus-messaging.org/, from
which there are links to the original Google code repository, more
documentation, and various userspace libraries.

There is a working repository with these patches applied to
Linux 2.6.37, available via:

git pull git://github.com/crazyscot/linux-2.6-kbus.git kbus-2.6.37

These patches have been applied in branch apply-patchset-20110318

In order to keep the size of individual patches down, the main code
has been split over several patches (0004..0009). With luck this
should also make it easier to understand what KBUS is trying to do.
