From e83e73f5b0f8de6a8978ba64185e80fdf48a2a63 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 14 May 2019 09:50:49 -0700 Subject: rcu/nocb: Leave ->cblist enabled for no-CBs CPUs As a first step towards making no-CBs CPUs use the ->cblist, this commit leaves the ->cblist enabled for these CPUs. The main reason to make no-CBs CPUs use ->cblist is to take advantage of callback numbering, which will reduce the effects of missed grace periods which in turn will reduce forward-progress problems for no-CBs CPUs.
