Actually I think we do not need a PR for this: as a committer anyone can do the docs jar packaging -> pasting to kafka-site and push to asf-site branch. You can follow this step of the release process here:

Can't i just merge this PR? The process there seems more about creating a new version for a release, i.e, i don't want to update everything

[guozhangwang]

Generally speaking separate commits on kafka and kafka-site may have the risk of diverge on these two repos if people forget to make the corresponding changes to kafka-site while pushed to kafka etc.

Re-package the docs to kafka-site won't update everything as long as it is from the corresponding branch (i.e. 0.11.0 in this case), the affected files should only be those gets modified by the patch on kafka.

@guozhangwang , yep had the discussion with @ijuma today. Managed to break everything in the process due to changes that weren't in kafka that were in kafka-site and changes in kafka that were broken. Anyway, it was fun! ;-)
