In order to prevent flow counters stats work function from traversing whole flow counters tree while searching for deleted flow counters, new list to store deleted flow counters will be added to struct mlx5_fc_stats. However, the flow counter structure itself has no space left to store any more data in first cache line. To free space that is needed to store additional list node, convert current addlist double linked list (two pointers per node) to atomic single linked list (one pointer per node). Lockless NULL-terminated single linked list data type doesn't require any additional external synchronization for operations used by flow counters module (add single new element, remove all elements from list and traverse them). Remove addlist_lock that is no longer needed.

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.
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.
