Since I have systems with multiple omogeneous scsi boards (either
Ultrastor or DPT), it is a very valuable feature for my driver
development to test the drivers as modules, but to have the
system running I must have the driver in the kernel as well
because all the scsi boards are from the same brand and I do not
use IDE. Anyway if the driver is properly written and the only
external data are the legitimate scsi structures, for the kernel
loading it as a module is just the same of another scsi driver
and there are no conflicts. If it does not work, it is an
indication that either the driver need a fix or that the
scsi structures are not general enough and need to be
circumvented in some way by the driver.
Another good reason is that on an external bus I have extremely
various scsi devices, not turned on all the time, and I need to
plug and unplug them in a clean way without rebooting the system.
I do not see any justification why the above should be allowed
if I had two different brands of scsi controllers but forbidden
if all the scsi boards have the same brand.
Anyway if the patch could take into account only modules there should
be no conflicts at all.
