An r-b is a formal statement like a s-o-b. From
Documentaion/SubmittingPatches:

        Reviewer's statement of oversight

        By offering my Reviewed-by: tag, I state that:

         (a) I have carried out a technical review of this patch to
             evaluate its appropriateness and readiness for inclusion into
             the mainline kernel.

         (b) Any problems, concerns, or questions relating to the patch
             have been communicated back to the submitter.  I am satisfied
             with the submitter's response to my comments.

         (c) While there may be things that could be improved with this
             submission, I believe that it is, at this time, (1) a
             worthwhile modification to the kernel, and (2) free of known
             issues which would argue against its inclusion.

         (d) While I have reviewed the patch and believe it to be sound, I
             do not (unless explicitly stated elsewhere) make any
             warranties or guarantees that it will achieve its stated
             purpose or function properly in any given situation.

If you're asking "why is this needed?" it does _not_ deserve an r-b on
a pretty fundamental level since it clearly violates c) 1) above.

Please don't just go through the motions when doing review.

Thanks, Daniel
