Mauro,

I think it's wrong that you alter signatures. You did this:

Reviewed-by: <mkrufky@xxxxxxxxxxx <mailto:mkrufky@xxxxxxxxxxx>>

But I provided this:

Signed-off-by: Michael Krufky <mkrufky@xxxxxxxxxxx>

I sign the patch, because I have handled it in my -stable queue.


You put my email address without my name!

A signature is sacred and nobody should fudge it.

Please fix it before you send to -git.

-Mike
