explain the hidden scsi_wait_scan Kconfig variable 



People keep sending patches to expose CONFIG_SCSI_WAIT_SCAN as a tunable
item.  These patches aren't accepted upstream, so let's stop the ongoing
irritation of people due to the unconditionally installed module and its
Kconfig symbol.

# 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.
