Patch series "add KSM selftests". Introduce selftests to validate the functionality of KSM. The tests are run on private anonymous pages. Since some KSM tunables are modified, their starting values are saved and restored after testing. At the start, run is set to 2 to ensure that only test pages will be merged (we assume that no applications make madvise syscalls in the background). If KSM config not enabled, all tests will be skipped. This patch (of 4): Add check_ksm_merge() function to check the basic merging feature of KSM. First, some number of identical pages are allocated and the MADV_MERGEABLE advice is given to merge these pages. Then, pages_shared and pages_sharing values are compared with the expected numbers using assert_ksm_pages_count() function. The number of pages can be changed using -p option.

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.
