The last user of .tunnel_sock is pppol2tp_connect() which defensively uses it to verify internal data consistency. This check isn't necessary: l2tp_session_get() guarantees that the returned session belongs to the tunnel passed as parameter. And .tunnel_sock is never updated, so checking that it still points to the parent tunnel socket is useless; that test can never fail.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
