The plan is to incrementally backport bug fixes and optimizations from
bcache-dev to upstream for the foreseeable future.

As an ethousiastic bcache user myself I would be very happy if there's a
transition plan! :-)

Would it make sense to call this bcache2 and merge both into the linux 
tree once bcache2 is stable enough for broader testing?

Yeah that might be what happens.

To the extent possible, you could reuse common code paths and simplify the 
backporting of bug fixes into the existing stable branch.

Code reuse is problematic because struct bkey itself changes, a lot of the code
that's factored out as a library now depends on the specific layout of struct
bkey :/

Gonna try and backport as much as possible that doesn't require changing the on
disk format when I have time, though.
