Miaohe Lin 8ea2f86cea mm/z3fold: remove unneeded page_mapcount_reset and ClearPagePrivate
Page->page_type and PagePrivate are not used in z3fold.  We should remove
these confusing unneeded operations.  The z3fold do these here is due to
referring to zsmalloc's migration code which does need these operations.

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 Restructured Text 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.
