Thanks for trying this out. I should've mentioned how best to test this.
You're going to want to add:
export MOUNT_OPTIONS="-o space_cache=v2"
to local.config. So I don't think this actually tested the free space
tree (although it looks like it might have turned up something else).

I recommend `./check -g auto` instead in order to run the relevant
generic tests as well.

So we're definitely not using the free space tree.

That's weird. This was on a freshly created filesystem? If you don't
mind, could you try reproducing this without my patch series and making
a new thread if it still happens?
