Linux kernel source tree

When we stumble over a fully-mapped mlocked THP in the deferred shrinker, it does not make sense to try to detect whether it is underused, because try_to_map_unused_to_zeropage(), called while splitting the folio, will not actually replace any zeroed pages by the shared zeropage. Splitting the folio in that case does not make any sense, so let's not even scan to check if the folio is underused.

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.
