Parent article: Bcache: Caching beyond just RAM
This approach of intercepting bio requests in the background allows us to start and stop caching on the fly, to add and remove cache devices, and to boot with or without bcache
Am I right in thinking this will only be possible once the checksumming feature mentioned at the bottom of the article is in place? Otherwise, what would stop the cache returning an out-of-date copy of a block modified while it was offline?
