Hi Mark,

Im able to replicate and confirm the following patch fixes it:

https://lore.kernel.org/linux-ext4/5bb9041471dab8ce870c191c19cbe4df57473be8.1772381213.git.ritesh.list@gmail.com/

I believe the previous test's cleanup is not going through properly
causing the mballoc test to fault.

Thanks,
