On cleanup, when the node is the last child of parent then it calls to
tree_put_node on the parent, if the parent's reference count
is decremented to 0 (for e.g. when deleting last destination of FTE)
then we free the parent as well and vice versa. In such a case
we will try to free the parent node again.
Increment the parent reference count before cleaning it's children
will prevent implicit release of the parent object.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
