Subject: [PATCH] md/raid5: Replace deprecated CPU-hotplug functions.
References: bsc#1189998 (PREEMPT_RT prerequisite backports)
Patch-mainline: v5.15-rc1
Git-commit: 252034e03f04e54acfb5f5924dd26ae638e3215e
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.
