Subject: [PATCH] Documentation: Replace deprecated CPU-hotplug functions.
References: bsc#1189998 (PREEMPT_RT prerequisite backports)
Patch-mainline: v5.15-rc1
Git-commit: c7483d823ee0da31e42d32e51a752f667a059735
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.
