I agree, but usually you wouldn't partition an MD-RAID either, would
you? OSDs are still holding (so far) ordinary filesystems locally
mounted on the nodes (except for BlueStore AFAIK).
  

I have partitioned MD-RAID before, works just fine.

Yes, sure. It just doesn't feel right, my  grey-bearded Unix instinct
tingles :)

The question still remains, can bcache be patched that it allocates
the right minor in the kernel so that it allows for partitions.

Even looks easy... As Sam Yaple made a patch.

I'm not a kernel nor bcache developer, just looking for somebody who
would be willing to do this. Happy to assist, support and test!

Well if I have some time I may give it a try next week :)
