Patch series "Cleanup and fixup for ksm". This series contains cleanups to remove unnecessary VM_BUG_ON_PAGE and dedicated macro KSM_FLAG_MASK. Also this fixes potential missing rmap_item for stable_node which would result in failed rmap_walk_ksm(). More details can be found in the respective changelogs. This patch (of 4): The same VM_BUG_ON_PAGE() check is already done in the callee. Remove these extra caller one to simplify code slightly.

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.
