Add selftests covering the following cases: - A static or global subprog called from within a RCU read section works - A static subprog taking an RCU read lock which is released in caller works - A static subprog releasing the caller's RCU read lock works Global subprogs that leave the lock in an imbalanced state will not work, as they are verified separately, so ensure those cases fail as well.

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.
