Devlink used to have two global locks: devlink lock and port lock,
our lock ordering looked like this:
devlink lock -> driver's pf->lock -> devlink port lock
After recent changes port lock was replaced with per-instance
lock. Unfortunately, new per-instance lock is taken on most
operations now. This means we can only grab the pf->lock from
the port split/unsplit ops. Lock ordering looks like this:
devlink lock -> driver's pf->lock -> devlink instance lock
Since we can't take pf->lock from most devlink ops, make sure
nfp_apps are prepared to service them as soon as devlink is
registered. Locking the pf must be pushed down after
nfp_app_init() callback.
The init order looks like this:
nfp_app_init
devlink_register
nfp_app_start
netdev/port_register
As soon as app_init is done nfp_apps must be ready to service
devlink-related callbacks. apps can only register their own
devlink objects from nfp_app_start.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
