Date: Tue, 3 Aug 2021 16:15:53 +0200 [thread overview] Message-ID: <20210803141621.780504-11-bigeasy@linutronix.de> (raw) In-Reply-To: <20210803141621.780504-1-bigeasy@linutronix.de> 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.
