From 26730f55c2842b4ee06a5307d58265db7dd26065 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 21 Apr 2015 09:22:14 -0700 Subject: [PATCH] rcu: Make RCU able to tolerate undefined CONFIG_RCU_KTHREAD_PRIO This commit updates the initialization of the kthread_prio boot parameter so that RCU will build even when CONFIG_RCU_KTHREAD_PRIO is undefined. The kthread_prio boot parameter is set to CONFIG_RCU_KTHREAD_PRIO if that is defined, otherwise to 1 if CONFIG_RCU_BOOST is defined and to zero otherwise. This commit then makes CONFIG_RCU_KTHREAD_PRIO depend on CONFIG_RCU_EXPERT, so that Kconfig users won't be asked about CONFIG_RCU_KTHREAD_PRIO unless they want to be.
