      Description

      CollectionLock invariants that an appropriate DBLock is held. Lock-free reads do not take that DBLock. Also, lock-free reads do not want to take any collection or database level locks, including <db>.system.views collection locks. We need to remove them, or find another solution if needs be. Looks like SERVER-40992 originally added the view collection locks.
