Thank you for your kind words.

While fstests cannot officially add out-of-tree filesystems to its upstream
support matrix, there is certainly no problem with out-of-tree projects
forking the codebase to maintain and use it for their own needs, that's what
open source is all about.

At the same time, if you ever make general improvements, bug fixes, or
enhancements to tools like fsx or the replay utilities, you are always more
than welcome to send them back to the mainline fstests mailing list as patches.
Contributions and feedback are always appreciated.

Thanks,
Zorro
