Yes, correct. The on disk format changes in bcache-dev are just too deep to feasibly write backwards compat code, unfortunately. And the on disk format is still in flux - for just a bit longer hopefully though, right now I'm working on a pretty major revamp that's getting close to done (self describing and packed metadata). This revamp is making the on disk format _much_ more flexible though, and cleaning up a lot of stuff at the same time. -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
