Please drop this one. Ross posted a fix for the same thing three days
before mine, which I missed:
https://lore.kernel.org/xen-devel/20260918125205.374168-1-ross.lagerwall@xxxxxxxxxx/
His patch also drops the NP_ENABLE writes, so it covers strictly more
than mine. Sorry for the noise.
Worth mentioning: I have an XTF test that catches this issue.
