/proc/vmstat displays counters from various sources. It is easy to forget to add or remove a label when a new counter is added or removed. There is a BUILD_BUG_ON() function that catches missing labels. However, for some reason, it ignores extra labels. Let's make the check strict. This would help to catch issues when a counter is removed. Link: https://lkml.kernel.org/r/20250529110541.2960330-1-kirill.shutemov@linux.intel.com Signed-off-by: Kirill A.

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 reStructuredText 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.
