My initial reaction was that the function is somewhat superfluous,
so having a use case in the patch comment would be good:  why
can't userspace do the toggle itself?

On the other hand, I find it hard to object to such a small feature.
If that's the worst feature bloat in Linux this year, we're overdue
for a big party.  ;)
