Wei Yang a1802098ef maple_tree: fix mt_destroy_walk() on root leaf node commit `ea9b77f98d` upstream. On destroy, we should set each node dead. But current code miss this when the maple tree has only the root node. The reason is mt_destroy_walk() leverage mte_destroy_descend() to set node dead, but this is skipped since the only root node is a leaf. Fixes this by setting the node dead if it is a leaf.

README

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.
