active_work is a work that iterates over all possible SF devices which their SF port representors are located on different function, and in case SF is in active state, probes it. Currently, the active_work in active_wq is synced with mlx5_vhca_events_work via table_lock and this lock causing a bottleneck in performance. To remove table_lock, redesign active_wq logic so that it now pushes active_work per SF to mlx5_vhca_events_workqueues. Since the latter workqueues are ordered, active_work and mlx5_vhca_events_work with same index will be pushed into same workqueue, thus it completely eliminates the need for a lock.

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.
