With list.h lists, it is easy to test if a node is on a list, providing it was initialised and that it is removed with list_del_init(). This patch provides similar functionality for llist.h lists. init_llist_node() marks a node as being not-on-any-list be setting the ->next pointer to the node itself. llist_on_list() tests if the node is on any list. llist_del_first_init() remove the first element from a llist, and marks it as being off-list.

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.
