Yes, it's here (State: New):
https://lore.kernel.org/patchwork/patch/1024393/

This page says it was mailed to linux-mm mailing list too:
https://groups.google.com/forum/#!topic/kasan-dev/g8A8PLKCyoE

But I can't find linux-mm archives here:
http://vger.kernel.org/vger-lists.html

How can I add a tag to an existing change under review? Patchwork does
not show something like "add Tested-by: me tag" to me on the patch
page.

Patchwork shows Todo list on the main page with "Your todo list
contains patches that have been delegated to you". But I don't see an
option to delegate this patch to you either...
