14 the main devlink object is itself registered. The newer ``devl_*`` APIs assume
15 the devlink instance lock is already held. Drivers can take the instance
17 devlink netlink commands.
19 Drivers are encouraged to use the devlink instance lock for their own needs.
21 Drivers need to be cautious when taking devlink instance lock and
22 taking RTNL lock at the same time. Devlink instance lock needs to be taken
