Hi, This is a series on top of the patch "rcu/tree: Add basic support for kfree_rcu() batching". Link: http://lore.kernel.org/r/20190814160411.58591-1-joel@xxxxxxxxxxxxxxxxx It adds performance tests, some clean ups and removal of "lazy" RCU callbacks. Now that kfree_rcu() is handled separately from call_rcu(), we also get rid of kfree "lazy" handling from tree RCU as suggested by Paul which will be unused. This also results in a nice negative delta as well.
