Add tests for the improvement made to read operation on HWPOISON hugetlb page with different read granularities. For each chunk size, three read scenarios are tested: 1. Simple regression test on read without HWPOISON. 2. Sequential read page by page should succeed until encounters the 1st raw HWPOISON subpage. 3. After skip a raw HWPOISON subpage by lseek, read()s always succeed.

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.
