Isn't that going to disable all of SCSI? I think the intention may be to
drop hardware drivers and just use ide-scsi, although I might be
misreading the original intent.

There are a fair number of tape/CD/DVD devices out there which you might
run SCSI. I many cases will run SCSI or not at all.

I thought the intent was to make it unnecessary to run ide-scsi at all.  
There was talk about it awhile back on the list.  I've been burning CDs 
using ide cdrom support for several kernel revisions now.

I don't think it matters, the idea is to avoid all the low-level SCSI
menus in one place, without disabling the ability to handle ATAPI devices.
Using the ide-scsi or not still uses SCSI drivers AFAIK.

Have you checked/used them? I kind of wrote that off after a while, I
don't need more coasters :-( At the time I deferred testing the score was
CD: read okay burn failed, ide-floppy (ZIP in my case): ng, and tape: not
even visible. That was back around 2.5.52 or so, since ide-scsi seems to
work I haven't been motivated to care.

As I said, I've been using it successfully.  I've not tested ide-floppy 
since I don't have one, nor a tape.  I would rather not have to use 
ide-scsi if I can help it.  ide cd support is incompatible with ide-scsi 
cdrom support, so things are simpler if I can just cut out the scsi 
support entirely.

Since I have SCSI devices I'd rather make the ATAPI devices look SCSI than
have two sets of tools to do things. And two sets of drivers loaded, two
sources of possible bugs, etc. That just seems simpler to me.

Thanks for the input.

But as far as linux scsi is concerned, ide-scsi is a low-level SCSI driver. 

IDE and USB have there own Kconfig options that enable low-level SCSI
driver emulation outside of drivers/scsi, pcmcia does not, and there are
probably other exceptions.

The following is simpler, though I'm not suggesting anything like this be
applied, since we don't have consitency. If all of the low-level scsi
drivers and options were under drivers/scsi, and we could separate
emulated versus real, something like this might be OK:

I think this is a very good idea. In the long run this is one of those
matrix things, is SCSI on USB an entry in a menu of USB or SCSI? And until
we can access the option from either place and still have exactly one
option, we (someone) must decide which it is.

Clearly unless we do it both way at some time, some portion of the users
will find either choice unintuitive. What you propose is a step forward,
and if extensions are made in 2.7 which suggest rethinking, so be it.

Thanks for the patch, it's goin in my tree.
