Honestly, I don't see the point of this when it ends up just being
dead code basically immediately.

You don't actually support picking one or the other at build time,
just a hard switch-over.

That makes the old fscache driver useless. You can't say "use the old
one because I don't trust the new". You just have a legacy
implementation with no users.
