Fork of reMarkable kernel https://github.com/reMarkable/linux

The extent tree of the test fs is like the following:
BTRFS info (device (null)): leaf 16327509003777336587 total ptrs 1 free space 3919
item 0 key (4096 168 4096) itemoff 3944 itemsize 51
extent refs 1 gen 1 flags 2
tree block key (68719476736 0 0) level 1
^^^^^^^
ref#0: tree block backref root 5
And it's using an empty tree for fs tree, so there is no way that its
level can be 1.
For REAL (created by mkfs) fs tree backref with no skinny metadata, the
result should look like:
item 3 key (30408704 EXTENT_ITEM 4096) itemoff 3845 itemsize 51
refs 1 gen 4 flags TREE_BLOCK
tree block key (256 INODE_ITEM 0) level 0
^^^^^^^
tree block backref root 5
Fix the level to 0, so it won't break later tree level checker.
Fixes:

README
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.
