When you run `make-bcache -B <backing-dev> -C <cache-dev>` the utility writes the super block(s) of all the devices specified and exits. Then udev in conjunction with the bcache udev rules file will do the register etc. as needed to bring the device up. Thus if someone scripts bcache creation there is a race condition between when make-bcache runs and when the user that issued the command can use the newly created device. I think it might be better to have an option to wait until done with the tool or make the default behavior to wait until everything is actually done? Otherwise, people need to either do explicit udev settles, sleeps, sysfs polling, etc. to ensure operation is fully completed. Thoughts, suggestions?
