Let's explicitly flush the kernel's buffer cache on the whole block device once we ran "mkfs". This is necessary, because partition and whole block devices maintain separate buffer caches, and thus writing to one will not be visible on the other if cached there already, until the latter's cache is explicitly flushed. This is preparation for later adding support for probing file sytems also if we have no open partition block devices, and hence want to use the whole block device instead.
