      Description

      Call mdt_dom_check_and_discard() after mdt_object_unlock() to avoid possible deadlock if some third lock is conflicting with both like in the scenario below:

      • thread1: mdt_object_lock() with some bits
      • thread2: take conflicting lock and wait
      • thread1: mdt_dom_check_and_discard() with bits conflicting with thread2 causes deadlock.
