This series simplifies use of the lockdep-RCU API, all courtesy of Jakub Kicinski: 1. Un-hide lockdep_tasklist_lock_is_held() for !LOCKDEP. 2. Un-hide RCU lockdep maps for !LOCKDEP. 3. Un-hide networking lockdep_sock_is_held() for !LOCKDEP. 4. Remove broken definitions in sched and un-hide for !LOCKDEP. 5. Use a more appropriate lockdep helper in SRCU. 6. Provide dummy forward declaration of *_is_held() helpers. 7. Prevent RCU_LOCKDEP_WARN() from swallowing the condition.
