I couldn't figure out a predictable way to detach it properly. Even when doing it as early as possible in the boot sequence, it'd succeed anywhere from the first time I tried to seven reboots later. I actually ended up doing something very nasty, but very efficient: I simply dd zeroes to the beginning of the cache device, then reboot, and the kernel would no longer recognize the cache device, and I could continue normally. Not pretty by any standard (actually makes me feel like showering), but it works ;) -- 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
