Subject: [PATCH tip/core/rcu 0/6] SRCU updates for v5.14
Date: Tue, 11 May 2021 16:07:20 -0700 [thread overview]
Message-ID: <20210511230720.GA2894512@paulmck-ThinkPad-P17-Gen-1> (raw)
Hello!
This series provides some updates for SRCU, all courtesy of Frederic
Weisbecker.
1. Remove superfluous sdp->srcu_lock_count zero filling.
2. Remove superfluous ssp initialization for early callbacks.
3. Unconditionally embed struct lockdep_map.
4. Initialize SRCU after timers.
5. Fix broken node geometry after early ssp init.
6. Early test SRCU polling start.
Thanx, Paul
