[PATCH v3 resend 0/6] Implement call_rcu_lazy() and miscellaneous fixes

From: Joel Fernandes (Google)
Date: Mon Aug 08 2022 - 23:45:36 EST


Just a refresh of v3 with one additional debug patch. v3's cover letter is here:
https://lore.kernel.org/all/20220713213237.1596225-1-joel@xxxxxxxxxxxxxxxxx/

I just started working on this again while I have some time during paternity
leave ;-) So I thought I'll just send it out again. No other changes other
than that 1 debug patch I added on the top.

Next I am going to go refine the power results as mentioned in Paul's comments
on the last cover letter.

Joel Fernandes (Google) (5):
rcu: Introduce call_rcu_lazy() API implementation
rcuscale: Add laziness and kfree tests
fs: Move call_rcu() to call_rcu_lazy() in some paths
rcutorture: Add test code for call_rcu_lazy()
debug: Toggle lazy at runtime and change flush jiffies

Vineeth Pillai (1):
rcu: shrinker for lazy rcu
