I understood that is blocked pending outcome of the legal matters
raised by v10...  and that this is why you were asked not to post
v11 until they had been resolved.

To be honest given that [I wrote all of the C code][1] for the most
recent version of the patch and that I'd like to see the bug fixed,
then I will probably have to give up on co-authorship. Instead I can
post my code with a new comment and patch description and credit you
with a Reported-by:. That should take the pressure off in terms of
landing this bug fix.

However, the legal issues do still need to be resolved or there is a
risk that other upstream contributions from your company will be
delayed.


Daniel.
