Again, I'm not a fan of (c) as an option, but if done, then the
simplest model would appear to be:

 - remove the old fscache code, obviously disabling the Kconfig for it
for each filesystem, all in one fell swoop.

 - add the new fscache code (possibly preferably in sane chunks that
explains the parts).

 - then do a "convert to new world order and enable" commit
individually for each filesystem

but as mentioned, there's no sane way to bisect things, or have a sane
development history in this kind of situation.
