commit29de68c2b3upstream. Function radix_tree_insert() returns errors if the node hasn't been initialized and added to the tree. "kfree(node)" and return value "NULL" of node_get() help to avoid using unclear node in other calls. Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
