+# scsi_wait_scan is a loadable module which waits 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 buses before allowing the boot to
+# proceed.  (This method is not applicable if targets boot independently in
+# parallel with the initiator, or with transports with non-deterministic target
+# discovery schemes, or if a transport driver does not support scsi_wait_scan.)
+#
+# This symbol is not exposed as a prompt because little is to be gained by
+# disabling it, whereas people who accidentally switch it off may wonder why
+# their mkinitrd gets into trouble.
