Date: Tue, 3 Aug 2021 16:16:10 +0200 Message-Id: <20210803141621.780504-28-bigeasy@linutronix.de> In-Reply-To: <20210803141621.780504-1-bigeasy@linutronix.de> References: <20210803141621.780504-1-bigeasy@linutronix.de> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-crypto@vger.kernel.org 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.
