Whole refcount conversion was a long piece of work and the above people contributed to this code either as
writes or reviewers or both. I am primary writer of the code and I am handing patches in our tree and sending them out,
so how exactly the above should look like?

Please note that we have about 300 patches and if I have to modify each sign-off to
reflect who contributed to each commit in what particular way, I will go insane.

Best Regards,
Elena.
