Should I move to code to a new drivers/scsi/scsi_sense.c and add it to
drivers/scsi/Makefile as:

obj-$(CONFIG_BLK_SCSI_REQUEST)    += scsi_sense.o

Every place I want to use the code is already covered by
CONFIG_BLK_SCSI_REQUEST, so it seems like I just need to know where to
put the .c file. :P

I think this is so much saner than a SCSI select or dependency, so I'll
have to disagree with Martin and Christoph. Just put it in drivers/scsi,
if it's the location they care about.

I actually plan to remove CONFIG_BLK_SCSI_REQUEST in a merge window
or two.  The only users are scsi and the ide layer, (virtio_blk
support has already been accidentally disabled for a while), and getting
rid of it allows to to shrink and simply the scsi data structures.

But if you want this for now lets keep scsi_sense.c in drivers/scsi
but depend on CONFIG_BLK_SCSI_REQUEST, that is easy enough to fix up.
