Hmm, it would be great if there is a way we can initialize only the
needed disk. "add_disk" was called from sd_probe:
add_disk <-
sd_probe <-
driver_probe_device <-
__device_attach <-
bus_for_each_drv <-
...
So the solution might need come from initrd or a device driver? Maybe
we can use a new system configuration item. But it can save a lot of
memory if we do not need to initialize those devices.
