I didn't indicate which patches to add the tags to, sorry.
3/4 sounds like the right place.

If 4/4 is a clean-up only, no new tags apply to that.

Fixes seems to mean different things to different people. It's
OK to drop that tag, but I prefer to see a pointer to the broken
commit. That helps downstream consumers of the commit log to
identify which patches they should be pulling in.

You don't need to send again. Christian can add tags in his repo.

My objection is to the "# 6.10.x" comment -- that doesn't make sense
because for sure, the stable tree will have moved on by the time that
v6.13-rc opens.
