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