No, I did do that read path reworking, they should work. However, I haven't been focusing on or exercising the multi device stuff in quite awhile - my main priority has been making single device filesystems rock solid and finishing off compression and such. Tiering ought to work, but can you hold off on exercising anything else? e.g. the active/RO transition stuff - I'm going to have to spend a fair amount of time digging into that code and figuring out what makes sense when the time comes. The checksum error is highly concerning though - that was related to messing with cache0/state, correct? I think Christopher is using tiering with checksumming enabled, can you confirm? -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
