| From | Sebastian Andrzej Siewior <> | Subject | [PATCH 32/38] sched: Replace deprecated CPU-hotplug functions. | Date | Tue, 3 Aug 2021 16:16:15 +0200 |
| |
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.
