Just call it 'bfq', that doesn't conflict with anything that's
in the kernel already.

Rebase your patches on top of Linus current master, some of them
will need to change and some can be dropped.

And disentangle it completely from the old bfq, I don't want to see
nasty stuff like includes of .c files with prior defines modifying
behavior of functions.

When that's done, get it posted for review asap. I would imagine
we will go through a few postings and review cycles, and if we're
targeting 4.12 with this, then we should get the ball rolling
on that side.
