Looks fine to me. I'll add it to my large queue of changesets for
Paul to review/pull to marcelo's tree.
FWIW, I talked to a bunch of SCSI folks at OLS about DMA off the stack

seem to be the case. Nevertheless, I think we will always be fighting
poorly written drivers so this seems to be a great debug option.
