When a new extent buffer is allocated there are a few mandatory fields which need to be set in order for the buffer to be sane: level, generation, bytenr, backref_rev, owner and FSID/UUID. Currently this is open coded in the callers of btrfs_alloc_tree_block, meaning it's fairly high in the abstraction hierarchy of operations. This patch solves this by simply moving this init code in btrfs_init_new_buffer, since this is the function which initializes a newly allocated extent buffer. No functional changes.

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.
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.
