Eswitch implements its own locking by means of state_lock mutex and multiple fine-grained lock in containing data structures, and is supposed to not rely on rtnl lock. However, eswitch offloads num_flows type is a regular long long integer and cannot be modified concurrently. This is an implicit assumptions that mlx5 tc is serialized (by rtnl lock or any other means). In order to remove implicit dependency on rtnl lock, change num_flows type to atomic64 to allow concurrent modifications.

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.
