And is the previous filesystem still hosed for good then? Or mounting

It seems like the kernel caught and prevented the discard after the
end of the partition, so the data should be fine; scrubbing will tell

Without the patch at least, it's BUG time. This is what happens when
mounting the image.
It is also BUG time WITH the patch. Mount succeeds, but "btrfs fi
balance HOME" gives us:
