Subject: [PATCH tip/core/rcu 0/3] CPU hotplug changes for 4.9
Date: Mon, 22 Aug 2016 08:38:25 -0700 [thread overview]
Message-ID: <20160822153825.GA9242@linux.vnet.ibm.com> (raw)
Hello!
This series contains a few CPU-hotplug updates:
1. Provide exact tracking of incoming CPUs, which means that there
is now a definite point in the CPU-hotplug code at which RCU
starts paying attention to incoming CPUs.
2. Get rid of obsolete CPU_STARTING reference, courtesy of Sebastian
Andrzej Siewior.
3. Convert rcutorture's CPU-hotplug handling to use the shiny new
state machine, courtesy of Sebastian Andrzej Siewior.
Thanx, Paul
