and how to avoid things like that in the future. Do more recently
created btrfs filesystems have safeguards against damage that may occur
when a filesystem fills up?

Is there any possiblity to cancel the pending balance without mounting

I have also filed https://bugzilla.kernel.org/show_bug.cgi?id=115581
