This patch adds test coverage for resizing datasec maps. The first two subtests resize the bss and custom data sections. In both cases, an initial array (of length one) has its element set to one. After resizing the rest of the array is filled with ones as well. A BPF program is then run to sum the respective arrays and back on the userspace side the sum is checked to be equal to the number of elements. The third subtest attempts to perform resizing under conditions that will result in either the resize failing or the BTF info being cleared.

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.
