From: Sebastian Andrzej Siewior Date: Tue, 3 Aug 2021 14:16:04 +0000 (+0200) Subject: virtio_net: Replace deprecated CPU-hotplug functions. X-Git-Tag: v5.15~428^2~291 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a0d1d0f47e3193d6188869ae6bcf08a792f63cf6;p=platform%2Fkernel%2Flinux-starfive.git virtio_net: Replace deprecated CPU-hotplug functions. 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. Cc: "Michael S.
