After the commit 7fb1b252afb5 ("mm: shmem: add mTHP support for anonymous
shmem"), we can configure different policies through the multi-size THP
sysfs interface for anonymous shmem. But currently "THPeligible"
indicates only whether the mapping is eligible for allocating THP-pages as
well as the THP is PMD mappable or not for anonymous shmem, we need to
support semantics for mTHP with anonymous shmem similar to those for mTHP
with anonymous memory.

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.
