| 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 | |
