Subject: [PATCH 1/1] rcu: Fix build failure
Date: Fri, 18 Jul 2014 13:30:52 -0400	[thread overview]
Message-ID: <53C959CC.6030401@gmail.com> (raw)

Hi Paul,

While running the kvm rcutorture test scripts, I encountered a build failure caused by

Commit 918179699e4a ("rcu: Don't keep timekeeping CPU tick running for non-nohz_full= CPUs")

This commit fixes the failure. This is on top of paul/rcu/dev.
