I still prefer the original patch where EH is scheduled from the
translation layer. This seems unnecessarily intrusive to me. As I
wrote before, it's not like we have a clean translation anyway and I
think this better fits as impedance matching code in the translation
layer anyway. But, that said, this is a rather ugly piece of code
which is necessary just to work around the fact that we live under
scsi, so as long as it works, one way or the other probably doesn't
matter all that much (the reason why I prefer the previous one, as it
doens't try to be pretty and just gets it done), so it's Jeff's call.
Thanks.
