Yes, that is what I thought.

Both series have to do with reflogs, but they are logically pretty
independent. In particular, "Fix some problems with reflog expiration"
fixes problems that existed before mh/reflog-expire. And considering
that one topic is quite mature whereas the the other is just making its
debut, it seemed like yoking them together would slow down the first
topic for no good reason.

Stefan, I think you mean sb/atomic-push, not sb/atomic-push-fix, right?

I see all of these topics as pretty independent, though given that they
touch similar areas of the code they often have annoying (but small)
conflicts with each other.

I expected that mh/reflog-expire and sb/atomic-push would be merged
pretty early in the 2.4 cycle (they are both in next already). Junio, is
that not your plan?

Michael
