Subject: net: Replace deprecated CPU-hotplug functions.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=372bbdd5bb3fc454d9c280dc0914486a3c7419d5;p=linux.git

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.
