The EXT_STATS macro in fs/ext4/ext4_extents.h has been defined but never used in the codebase since its introduction. This patch removes it. Analysis: 1. No references found in fs/ext4/ or other kernel code. 2. No impact on compilation or functionality. 3. Git history shows it was never utilized.

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.
