I'm confused about what you meant by that--in the isw handler, the
raid_devs created in _create_rd are suppsoed to have

Actually, I had no idea that isw was creating extra raid_devs in
group_rd; from my perspective, I had simply thought that it made sense
for read_raid_dev to create all the raid_devs that were required and to
push all of those raid_devs through setup_rd, instead of creating one
raid_dev per disk in read_raid_dev and adding the rest later.  However,
it seems a little weird to me that under that scheme one doesn't see all
the raid_devs until after isw_group is called.

But, I suppose it wouldn't be too difficult to reroll the patches to do
it that way too.
