Mauricio Faria de Oliveira 3b52b9e31a mm/page_owner: add debugfs file 'show_handles'
Add the flag STACK_PRINT_FLAG_HANDLE to print a stack's handle number from
stackdepot, and add the file 'show_handles' to show just handles and their
number of pages.

This is similar to 'show_stacks', with handles instead of stack traces.

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.
