Yap.
Also, looking forward in the set, I see prctl_set() and that is also
done on current so should be ok.
In any case, yes, documenting the assumptions and expectations wrt
current here is a good idea.
If vm_munmap() returns -EINTR, mmap_lock is held by something else. That
lock should not be held forever. For other types of error, the loop stops.
Ok I guess. The subsequent WARN_ON_ONCE() looks weird too but that
should not fire, right? :)
Thx.
That should not fire.
