In preparation for adding support for SRCU, refactor the definitions of rcu-fence, rcu-rscsi, rcu-link, and rb by moving the po and po? terms from the first two to the second two. An rcu-gp relation is added; it is equivalent to gp with the po and po? terms removed. This is necessary because for SRCU, we will have to use the loc relation to check that the terms at the start and end of each disjunct in the definition of rcu-fence refer to the same srcu_struct location. If these terms are hidden behind po and po?, there's no way to carry out this check. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Paul E.

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.
