From 77a40f97030b27b3fc1640a3ed203870f0817f57 Mon Sep 17 00:00:00 2001 From: "Joel Fernandes (Google)" Date: Fri, 30 Aug 2019 12:36:32 -0400 Subject: rcu: Remove kfree_rcu() special casing and lazy-callback handling This commit removes kfree_rcu() special-casing and the lazy-callback handling from Tree RCU. It moves some of this special casing to Tiny RCU, the removal of which will be the subject of later commits. This results in a nice negative delta. Suggested-by: Paul E.
