It's an existing sysfs node, which was originally added by Dan in Sep 2018:
/sys/bus/nd/devices/nmem0/nfit/dirty_shutdown.

Before this patch, the node doesn't appear when Linux runs on Hyper-V,
and with this patch, the node can appear now.

However, indeed, the node and the other related nodes have not been
documented in Documentation/ABI/testing/sysfs-bus-nfit yet.

I suppose Dan would add that?

Thanks,
