I'm wondering whether we want it now that 2.4 is basically frozen, but
I don't think there was a strong case against it say 4 or 5 month ago.
OTOH given that success (or lack thereof) I had pushing core changes
through Marcelo the chances it had even if scsi folks ACKed wouldn't
have been too high.

I personally just don't care enough about 2.4 anymore, so I don't think
I'll invest major amounts of time into it.  Even though the scsi changes
you've done are fairly huge I'm wondering whether we should just throw
it all in anyway - given that you said you'll have to care for the 2.4
scsi stack for a longer time for RH and no one else seems to be interested
doing maintaince.
