[PATCH 0/5] kfree_rcu() additions for -rcu

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Joel Fernandes (Google) (5):
rcu/rcuperf: Add kfree_rcu() performance Tests
rcu/tree: Add multiple in-flight batches of kfree_rcu work
rcu/tree: Add support for debug_objects debugging for kfree_rcu()
rcu: Remove kfree_rcu() special casing and lazy handling
rcu: Remove kfree_call_rcu_nobatch()
