Add check_ksm_unmerge() function to verify that KSM is properly unmerging shared pages. For this, two duplicate pages are merged first and then their contents are modified. Since they are not identical anymore, the pages must be unmerged and the number of merged pages has to be 0. The test is run as follows: ./ksm_tests -U Link: https://lkml.kernel.org/r/c0f55420440d704d5b094275b4365aa1b2ad46b5.1626252248.git.zhansayabagdaulet@gmail.com Signed-off-by: Zhansaya Bagdauletkyzy <zhansayabagdaulet@gmail.com> Reviewed-by: Pavel Tatashin <pasha.tatashin@soleen.com> Reviewed-by: Tyler Hicks <tyhicks@linux.microsoft.com> Cc: Hugh Dickins <hughd@google.com> Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
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.
