Subject: [PATCH tip/core/rcu 1/3] documentation: Update sysfs path for rcu_cpu_stall_timeout
Date: Wed, 7 Jan 2015 09:10:20 -0800 [thread overview]

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.

So if you are 10 seconds into a 40-second stall, setting this
sysfs parameter to (say) five will shorten the timeout for the
