I don't care about inefficiency, I'm worried about correctness.  It's extremely
unlikely this fixes a true bug in the legacy MMU, but there's also no real
downside to adding the check.

Ping, in case this dropped off your radar.  Regardless of how we fix this goof,
it needs to get fixed in 5.16.

Something has happened to my home directory in the middle of tests running for this rc, and I can't really do anything about it until someone sees my ticket. :/ This is the Linux maintainer version of a dog eating my homework, I suppose.

Since there was another report of this, I'll just queue up this version and send it out.
