[$] The kdbuswreck
Few readers will have failed to notice by now that the attempted merging of
the kdbus interprocess communication system into the 4.1 kernel has failed
to go as well as its proponents would have liked. As of this writing, the
discussion continues and nothing has been merged. This article constitutes
an attempt to derive a bit of light from the massive amounts of heat that
have been generated so far, with a specific focus on the issue of metadata
and capabilities.
