I hardly dare to mention bsg here; but the is pretty similar to what it set
out to do ...
Except that:
a) we created a complete mess with bsg by overloading the scsi ioctls
with some of the transport stuff.
b) bsg would not work with existing tools. A character device that
accepts the same ioctl will just work.
... as would a bsg device which could accept said ioctl ...
Plus it feels a bit weird, having a generic command passthrough
character device which is then avoided in favour of a protocol-specific
command passthrough device.
Which we had been arguing for years with IHVs for _not_ doing it.
So what is different here?
