Soon we'll have to check if a devlink instance is alive after locking it. Convert to the by-instance dumping scheme to make refactoring easier. Most of the subobject code no longer has to worry about any devlink locking / lifetime rules (the only ones that still do are the two subject types which stubbornly use their own locking). Both dump and do callbacks are given a devlink instance which is already locked and good-to-access (do from the .pre_doit handler, dump from the new dump indirection). Note that we'll now check presence of an op (e.g. for sb_pool_get) under the devlink instance lock, that will soon be necessary anyway, because we don't hold refs on the driver modules so the memory in which ops live may be gone for a dead instance, after upcoming locking changes.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
