I did not follow exaclty why.

At any rate, that
makes
it a no brainer to change.
As this external thing certainly is not doing the check itself, to be
on the safe side we should enforce it in get_futex_key(). I agree with
you : If we want to maximize performance, we could say : The check
*must* be done by the caller.
Well we _control_ the API, so let's make it as clean and performant as
possible
from the start.
