The vhca event notifier consists of an atomic notifier for vhca state changes (used for SF events), multiple workqueues and a blocking notifier chain for delivering the vhca state change events for further processing. This patch moves the vhca notifier head outside of mlx5_init_one() / mlx5_uninit_one() and into the mlx5_mdev_init() / mlx5_mdev_uninit() functions. This allows called notifiers to grab the PF devlink lock which was previously impossible because it would create a circular lock dependency. mlx5_vhca_event_stop() is now called earlier in the cleanup phase and flushes the workqueues to ensure that after the call, there are no pending events. This simplifies the cleanup flow for vhca event consumers.

README
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 reStructuredText 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.
