Thanks for the analysis and the bug fix!

I asked Tom Zanussi and he kindly reviewed your patch and provided an
Acked-by tag for it, Tom, may I add a Reviewed-by: as well?

Joseph, can I have your Signed-off-by: tag, as documented in:

Documentation/SubmittingPatches

In the "12) Sign your work" section?

Thanks!
