Subject: [PATCH tip/core/rcu 0/7] Lockdep-RCU updates for v5.11

Hello!

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.

						Thanx, Paul
