No kidding.

Here's my understanding of the situation (please correct me if I'm wrong):

 - Original patches were submitted to the libc-alpha mailing list by 
Darren back in May 2010 (see 
https://sourceware.org/ml/libc-alpha/2010-05/msg00055.html and 
follow-ups). They can also be found under the "Show Obsolete" link for 
attachments in bugzilla (V2): 
https://sourceware.org/bugzilla/show_bug.cgi?id=11588

 - At the end of last year (November/2013?) you've submitted a copyright 
assignment on behalf of IBM for those patches.

 - A copyright assignment was submitted on behalf of National Instruments 
for the changes I've made and signed by relevant parties in March 2014 
(RMS for FSF and our VP of R&D for NI).

 - I have ported the original patch "[PATCH 1/6][BZ #11588] pi-condvars: 
add protocol support to pthread_condattr_t" to glibc 2.19 and now 2.20 and 
added the patches 4/6, 5/6, 6/6 in the latest submission.

I guess the question is do the original IBM patches need to be 
re-submitted to libc-alpha@sourceware.org in order to fulfill the 
copyright assignment requirements or is the original submission by Daren 
(linked above) sufficient? Hopefully somebody on the libc-alpha list can 
provide some guidance here.

Also we need somebody with access to confirm that the copyright.list was 
updated with the assignments.

Thanks,
  Gratian
