It looks mainline to me. It is far more relevant than most of the other
file systems we support and it doesn't mess up core code at all. It's a
loadable kernel module so the impact is basically nil, as well as being
useful to other folk writing file systems.

If you used their documentation and didn't do the reverse engineering or
read any ReplayTV code there shouldn't be any problems. The big danger is
if you reverse engineer their code and you write new code you may copy
their implementation even accidentally (or be held to have done so).
