[aclug-L] Re: Driver load order, two scsi adapters

[John Goerzen <jgoerzen@xxxxxxxxxxxx>]

This is actually the recommended method.  Note that you don't have to
go to all that work, just making it a module will be fine.

If you absolutely have to avoid modules, edit drivers/scsi/host.c and
rearrange the lines under builtin_scsi_hosts[].
