    Subject[PATCH 23/38] net: Replace deprecated CPU-hotplug functions.
    Date
    The functions get_online_cpus() and put_online_cpus() have been
    deprecated during the CPU hotplug rework. They map directly to
    cpus_read_lock() and cpus_read_unlock().

    Replace deprecated CPU-hotplug functions with the official version.
    The behavior remains unchanged.
