This patch adds a series of tests to verify the behavior of BPF_LDX and BPF_STX with BPF_B//W sizes in isolation. In particular, it checks that BPF_LDX zero-extendeds the result, and that BPF_STX does not overwrite adjacent bytes in memory. BPF_ST and operations on BPF_DW size are deemed to be sufficiently tested by existing tests.

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.
