I've noticed the patch was in WoA state since 2019/12/01, but there's
been quite a lot of traffic on this thread and a bunch of new patch
versions. So I've switched it to "needs review" - if that's not the
right status, let me know.

Also, the patch was moved forward mostly by Amit and Dilip, so I've
added them as authors in the CF app (well, what matters is the commit
message, of course, but let's keep this up to date too).

regards
