The simple use case I can think of is "I want a snapshot, but I
don't have rights to copy the MAC context". Or "I want to own it, but I
want to keep all the ACLs for other users".
Basically, if I'm adding another int argument to reflinkat(2), I
wanted to consider the future. Maybe define it as 1 or 0, and leave the
use of the other bits for future possibilities? If we're lucky, of
course, we never need future changes.
