cpu/hotplug: Provide lockdep_assert_cpus_held() Provide a stub function which can be used in places where existing get_online_cpus() calls are moved to call sites. This stub is going to be filled by the final conversion of the hotplug locking mechanism to a percpu rwsem. Signed-off-by: Thomas Gleixner <[email protected]> Tested-by: Paul E.
