Subject: [PATCH tip/core/rcu 0/7] kfree_rcu() updates for v5.6
Date: Mon, 9 Dec 2019 20:11:18 -0800 [thread overview]
Message-ID: <20191210041118.GA3115@paulmck-ThinkPad-P72> (raw)
Hello!
The following series disentangles kfree_rcu() from core RCU and also
provides batching, all courtesy of Joel Fernandes:
1. Add basic support for kfree_rcu() batching.
2. Add kfree_rcu() performance tests.
3. Make kfree_rcu() use a non-atomic ->monitor_todo.
4. Add multiple in-flight batches of kfree_rcu() work.
5. Add support for debug_objects debugging for kfree_rcu().
6. Remove kfree_rcu() special casing and lazy-callback handling.
7. Remove kfree_call_rcu_nobatch().
Thanx, Paul
