Firstly, there is no need to have a double pointer here as we're only
walking the vmlist and not modifying it.

Secondly, for the same reason, we don't need a write lock but only a

nothing else.

Lastly, the reason for holding a lock is not what the comment says, so
let's remove that misleading piece of information.
