Hi Andrew, Thank you for looking into this.
> Are there any known userspace-visible runtime effects of this? Yes. I'm trying to fix this because it caused kernel panic on a VM with DAX in kata-containers project: https://github.com/kata-containers/kata-containers/commit/1c154b4c15cfc63e06ad1c48a801064677e874e2 I'll add kernel panic message in the commit log like patch v2: https://lore.kernel.org/all/[email protected]/ Thank you.
