I'm not sure about this part. We've already decremented, so the freed bit is
accounted for against the batch. Returning true here may double-count the freed

Yes, we may wake up waiters unnecessarily frequently. But that's a
performance issue at worst and only if it happens frequently. So I don't
think it matters in practice (famous last words ;).
Ok, let's go with that. Do you want to send the patch? I have a follow-up fix
for batched tagging that depends on this.
I think Kuai will do that. But if not, I can certainly take his patch and
resubmit it with the fixup.
Sorry that I'm too busy with work stuff recently, I can do that in a few
weeks. In the meantime, feel free go on without me.
Thanks,
Kuai
