From 933dfbd7c437bbbf65caae785dfa105fbfaa8485 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 2 May 2017 08:48:33 -0700 Subject: rcu: Open-code the rcu_cblist_n_lazy_cbs() function Because the rcu_cblist_n_lazy_cbs() just samples the ->len_lazy counter, and because the rcu_cblist structure is quite straightforward, it makes sense to open-code rcu_cblist_n_lazy_cbs(p) as p->len_lazy, cutting out a level of indirection. This commit makes this change. Reported-by: Ingo Molnar Signed-off-by: Paul E.
