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 and they believe it's all gone in 2.6. I double-checked and that does 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.
