Subject: [patch net-next 4/4] net: devlink: enable parallel ops on netlink interface

From: Jiri Pirko <jiri@...dia.com>

As the devlink_mutex was removed and all devlink instances are protected
individually by devlink->lock mutex, allow the netlink ops to run
in parallel and therefore allow user to execute commands on multiple
devlink instances simultaneously.
