Josef Bacik d7c9e1be28 btrfs: fix uninitialized parent in insert_state
I don't know how this isn't caught when we build this in the kernel, but
while syncing extent-io-tree.c into btrfs-progs I got an error because
parent could potentially be uninitialized when we link in a new node,
specifically when the extent_io_tree is empty.  This means we could have
garbage in the parent color.  I don't know what the ramifications are of
that, but it's probably not great, so fix this by initializing parent to
NULL.  I spot checked all of our other usages in btrfs and we appear to
be doing the correct thing everywhere else.

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.
