Subject: [PATCH tip/core/rcu 0/7] kfree_rcu() updates for v5.6
Date: Mon, 9 Dec 2019 20:11:18 -0800
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
