I'm starting to get tired of seeing new features be added to this chunk
of code, and the other related bits, without any noticable movement
toward getting it merged into the mainline tree.

So, I'm going to take a stance here and say, no more new features until
it gets merged into the "real" part of the kernel tree, as you all
should not be spinning your wheels on new stuff, when there's no
guarantee that the whole thing could just be rejected outright tomorrow.

I'm sorry, I know this isn't fair for your specific patch, but we have
to stop this sometime, and as this patch adds code isn't even used by
anyone, its a good of a time as any.
