l2tp_session_queue_purge is used during session shutdown to drop any skbs queued for reordering purposes according to L2TP dataplane rules. The BUG_ON in this function checks the session magic feather in an attempt to catch lifetime bugs. Rather than crashing the kernel with a BUG_ON, we can simply WARN_ON and refuse to do anything more -- in the worst case this could result in a leak. However this is highly unlikely given that the session purge only occurs from codepaths which have obtained the session by means of a lookup via. the parent tunnel and which check the session "dead" flag to protect against shutdown races. While we're here, have l2tp_session_queue_purge return void rather than an integer, since neither of the callsites checked the return value.

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.
