But every time I reboot, all bcache devices just disappear, and doesn't come up until `partprobe` being executed manually. Is there any method to let bcache bring those devices up automatically when the system is up? The `partprobe` workaround isn't ideal as most applications will fail due to the non-existent device. I have tried to adjust some module load configurations, but it did not work. Many thanks
