Patch series "Shmem mTHP controls and stats improvements", v3. This is a small series to tidy up the way the shmem controls and stats are exposed. These patches were previously part of the series at [2], but I decided to split them out since they can go in independently. This patch (of 2): Let's move count_mthp_stat() so that it's always defined, even when THP is disabled. Previously uses of the function in files such as shmem.c, which are compiled even when THP is disabled, required ugly THP ifdeferry. With this cleanup, we can remove those ifdefs and the function resolves to a nop when THP is disabled. I shortly plan to call count_mthp_stat() from more THP-invariant source files.

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.
