List of flows attached to hairpin entry is used as implicit reference counter (hairpin entry is deallocated when list becomes free) and as a mechanism to obtain hairpin entry that flow is attached to (through list head). This is not safe when concurrent modification of list of flows attached to hairpin entry is possible. Proper atomic reference counter is required to support concurrent access. As a preparation for extending hairpin with reference counting, extract code that deletes hairpin entry into standalone function. In order to remove this dependency on external locking, extend hairpin entry with reference counter to manage its lifetime and extend flow structure with direct pointer to hairpin entry that flow is attached to.

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.
