This is what the current documentation looks like.

#ifdef CONFIG_MM_OWNER
        /*
         * "owner" points to a task that is regarded as the canonical
         * user/owner of this mm. All of the following must be true in
         * order for it to be changed:
         *
         * current == mm->owner
         * current->mm != mm
         * new_owner->mm == mm
         * new_owner->alloc_lock is held
         */
        struct task_struct __rcu *owner;
#endif

Do you want me to document the fork/exit case?
