In scsi_cmnd there's an element called host_scribble. The name and the
comment by it were sufficiently confusing that I didn't realise that this
field is basically for the host's private data. Any objections to something
like this, assuming I also submit a patch that converts all the drivers?

(the only remaining references to scsi_malloc are in comments ... I'll
submit a different patch to remove those too)

"Next the statesmen will invent cheap lies, putting the blame upon
the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince
himself that the war is just, and will thank God for the better sleep
he enjoys after this process of grotesque self-deception." -- Mark Twain
