From 84596ccbf102644c846e050caf4714447f083206 Mon Sep 17 00:00:00 2001 From: Xie XiuQi Date: Tue, 11 Nov 2014 12:03:26 +0800 Subject: [PATCH] documentation: Update sysfs path for rcu_cpu_stall_timeout Commit 6bfc09e2327d ("rcu: Provide RCU CPU stall warnings for tiny RCU") moved the rcu_cpu_stall_timeout module parameter from rcutree.c to rcupdate.c, but failed to update Documentation/RCU/stallwarn.txt. This commit therefore repairs this omission. commit 96224daa16d6 ("documentation: Update sysfs path for rcu_cpu_stall_suppress") updated the path for rcu_cpu_stall_suppress, but failed to update for rcu_cpu_stall_timeout.
