reiser4 was never in the kernel and the odds of it ever making it there
were about zero (coding style issues and many other things that pissed
Linux off). And that was in the days when Hans was physically located
in a place where he was allowed to code.

For all practical purposes Reiser4 is dead. I haven't heard a peep out
of anyone claiming to maintain it for a few years now.
