From d1ec4c34c7a9f328e43ea87522119258194f28f8 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 13 May 2015 10:41:58 -0700 Subject: rcu: Drop RCU_USER_QS in favor of NO_HZ_FULL The RCU_USER_QS Kconfig parameter is now just a synonym for NO_HZ_FULL, so this commit eliminates RCU_USER_QS, replacing all uses with NO_HZ_FULL.
