Subject: [PATCH rcu 0/7] RCU-related lockdep changes for v6.4
Date: Thu, 16 Mar 2023 20:13:32 -0700	[thread overview]
Message-ID: <20230317031339.10277-1-boqun.feng@gmail.com> (raw)

Hi,

This series enables deadlock detection for srcu_read_lock() vs
synchronize_srcu().

Again, my first time helping prepare PR, so please take a careful look
and yell at me if there is something wrong. Thanks a lot!

You will also be able to find the series at:

	https://github/fbq/linux rcu/lockdep.2023.03.12a

top commit is:

	24390de55773	

List of changes:

Boqun Feng (4):
  locking/lockdep: Introduce lock_sync()
  rcu: Annotate SRCU's update-side lockdep dependencies
  locking: Reduce the number of locks in ww_mutex stress tests
  locking/lockdep: Improve the deadlock scenario print for sync and read
    lock

Paul E. McKenney (3):
  rcutorture: Add SRCU deadlock scenarios
  rcutorture: Add RCU Tasks Trace and SRCU deadlock scenarios
  rcutorture: Add srcu_lockdep.sh
