The log_root passed to walk_log_tree is guaranteed to have its root_key.objectid always be BTRFS_TREE_LOG_OBJECTID. This is by merit that all log roots of an ordinary root are allocated in alloc_log_tree which hard-codes objectid to be BTRFS_TREE_LOG_OBJECTID. In case walk_log_tree is called for a log tree found by btrfs_read_fs_root in btrfs_recover_log_trees, that function already ensures found_key.objectid is BTRFS_TREE_LOG_OBJECTID.

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.
