We were having corruption issues that were tied back to problems with the extent tree. In order to track them down I built this tool to try and find the culprit, which was pretty successful. If you compile with this tool on it will live verify every ref update that the fs makes and make sure it is consistent and valid. I've run this through with xfstests and haven't gotten any false positives.

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.
