Christian Brauner 67d676bb13 rculist: add list_bidir_{del,prev}_rcu()
Currently there is no primitive for retrieving the previous list member.
To do this we need a new deletion primitive that doesn't poison the prev
pointer and a corresponding retrieval helper. Note that it is not valid
to ues both list_del_rcu() and list_bidir_del_rcu() on the same 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 reStructuredText 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.
