Subject: [PATCH] kernel/cpu: Distinctive name for cpu_hotplug.dep_map
Date: Wed,  3 Feb 2016 16:24:28 +0200	[thread overview]
Message-ID: <1454509468-10627-1-git-send-email-joonas.lahtinen@linux.intel.com> (raw)

Use distinctive name for cpu_hotplug.dep_map to avoid the actual
cpu_hotplug.lock appearing as cpu_hotplug.lock#2 in lockdep splats.
