Hello, Hannes.
Sorry about the delay.

ata_dev_classify() just uses the 'lbah' and 'lbam'

I wonder whether it'd easier to just make sas code pass in
ata_taskfile instead? The interface which takes three consecutive
u8's is kinda error-prone.
Well, yes, in principle. I was looking into that, too.
But then I figured that moving to ata_taskfile would be a major overhaul
for libsas, which would be quite beyond scope here.
And all for a puny little patch.

Are these changes covered by the patch description? Looks like the
patch is mixing two separate logical changes.
Okay, I'll be splitting them up.
Cheers,
Hannes
