mm: Fully initialize invalidate_lock, amend lock class later
The function __init_rwsem() is not part of the official API, it just a helper function used by init_rwsem(). Changing the lock's class and name should be done by using lockdep_set_class_and_name() after the has been fully initialized. The overhead of the additional class struct and setting it twice is negligible and it works across all locks. Fully initialize the lock with init_rwsem() and then set the custom class and name for the lock.
