No worries, I haven't forgotten the checkpatch thing but the line is
81 chars and I just didn't want to split it because of _one_ char. The
benefit of readability of having it on one line should be more important
than one stupid static rule. I think we should relax it if enforcing it
worsens readability...

               int blocks = (blk_rq_bytes(rq) - rq->resid_len) /
			     tape->blk_size;

Now this looks awful, IMHO. I'd much rather not listen to checkpatch
here.
