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).
Anyway bcache would mostly make sense for the journal, much less for
the data section, so wouldn't it better to use bcache (or flash) for
journal/metadata only?
