Alice Ryhl 56b1852e82 rust: maple_tree: add MapleTreeAlloc
To support allocation trees, we introduce a new type MapleTreeAlloc for
the case where the tree is created using MT_FLAGS_ALLOC_RANGE.  To ensure
that you can only call mtree_alloc_range on an allocation tree, we
restrict thta method to the new MapleTreeAlloc type.  However, all methods
on MapleTree remain accessible to MapleTreeAlloc as allocation trees can
use the other methods without issues.

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.
