Subject: [PATCH 01/38] Documentation: Replace deprecated CPU-hotplug functions.
Date: Tue, 3 Aug 2021 16:15:44 +0200 [thread overview]
Message-ID: <20210803141621.780504-2-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().
Update the documentation accordingly.
