However, I haven't tested it yet but I intend to later this week.

I've tested libnvdimm-pending which includes this series on my setup and
everything works great.

Just wondering in a difference scenario where pmem pages are exported to
a KVM guest, and then by mistake the user issues "ndctl destroy-namespace -f",
will the kernel wait indefinitely until the user figures out to kill the guest
and release the pmem pages?

thanks,

Thanks,
