* This is a simple module to wait until all the async scans are
* complete. The idea is to use it in initrd/initramfs scripts. You
* modprobe it after all the modprobes of the root SCSI drivers and it
* will wait until they have all finished scanning their busses before
* allowing the boot to proceed
