I asked Khandelwal to send this patch upstream after we did an internal
review for it (I think I also asked him to send this out after v6.1-rc1
is released but whatever).

I think the bot noticed the v4 he sent earlier that was the same we
reviewed internally.

I was planning to pick this up after the merge window closes if there
are no objections.
