In v4.7 commit52b6f46bc1("mm: /proc/sys/vm/stat_refresh to force vmstat update") introduced vmstat_refresh(), with its vmstat underflow checking; then in v4.8 commit75ef718405("mm, vmstat: add infrastructure for per-node vmstats") split NR_VM_NODE_STAT_ITEMS out of NR_VM_ZONE_STAT_ITEMS without updating vmstat_refresh(): so it has been missing out much of the vmstat underflow checking ever since. Reinstate it. Thanks to Roman Gushchin <guro@fb.com> for tangentially pointing this out.

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.
