Thanks, Grant!

If I may, I'll add something like this to the commit log:

Acked-by: Grant Likely <grant.likely@...retlab.ca> (minus two
Reported-by issues)

And then we could fix those two issues in two subsequent patches
(carrying your Reported-by) so reviewing the change would be much
easier, and we don't end up changing code (that has been lying in
linux-next) just before it is sent it to Linus.

Thanks a lot for your review!
Ohad.
