In btrfs_orphan_cleanup the final 'if (ret) goto out' cannot ever be executed. This is due to the last assignment to 'ret' depending on the return value of btrfs_iget. If an error other than -ENOENT is returned then the loop is prematurely terminated by 'goto out'. On the other hand, if the error value is ENOENT then a subsequent if branch is executed that always re-assigns 'ret' and in case it's an error just terminates the loop. 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.
