Sadly, while it has some clear use cases, AF_BUS is not part of the
mainline kernel, it remains an out-of-tree patch...
It was added to a patched third-party 3.4.x kernel yesterday, as part
of the LTSI (used only by a tiny minority):
https://lwn.net/Articles/533534/ . That might speed up the inclusion
of AF_BUS to mainline, only time will tell.
