The only thing the passed root is used for is: 1. get a reference to the fs_info and to 2. call trace_btrfs_transaction_commit. We can achieve 1) by simply referring to the fs_info from passed trans object. As far as 2) is concerned cleanup_transaction is called from only one place and the 'root' argument passed is the one from the trans handle. No functional changes.

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.
