[ Upstream commit 6cb7f0b8c9 ]
We already have the extent buffer's level in an argument, there's no need
to first ensure the extent buffer's data is loaded (by calling
btrfs_read_extent_buffer()) and then call btrfs_header_level() to check
the level. So use the level argument and do the check before calling
btrfs_read_extent_buffer().

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.
