Matt Dillon’s added fsstress in src/test/stress/fsstress. This tool has been found useful before. Commit message quoted here: “Add the filesystem/NFS stress tester program, adapted for BSD by Jordan H ubbard of Apple, originally written by Silicon Graphics, Inc, and modified by many people, including the SUSE Linux project.”
