Subject: cpu/hotplug: Get rid of CPU_STARTING reference
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=0c6d4576c45736f829dc3390ac95181b2ed21bc7;p=deliverable%2Flinux.git

cpu/hotplug: Get rid of CPU_STARTING reference

CPU_STARTING is scheduled for removal. There is no use of it in drivers
and core code uses it only for compatibility with old-style CPU-hotplug
notifiers.  This patch removes therefore removes CPU_STARTING from an
RCU-related comment.
