First, I apologize if my writing is a bit incoherent.  I'm recovering from
surgery, and the pain medication I'm on is very strong.

However, when I saw this thread, it reminded me of an idea I had tossed
around with Eric Youngdale a while back.  The idea goes something like
this:

Basically, the way HBA drivers are loaded dynamically in linux now is that
the scsi layer requests a module by the name of scsi_hostadaptor.  If
there are multiple modules to be loaded, then a series of pre-load
directives must be placed in the conf.modules file to make them all load
in the correct order.

I propose the following:  SCSI HBA drivers are requested by a series of
names like scsi_host_0, scsi_host_1, etc.  These HBA drivers would be
loaded in order when probing, but can be removed and re-loaded on demand
more easily than under the current system.  Also, changing the order that
HBA drivers are loaded in is easier.

Any thoughts?  I realize that a change like this is too late for 2.4, but
perhaps for 2.5?
