fs_bench benchmarks the performance of Landlock's path walk by exercising it in a scenario that amplifies Landlock's overhead: * Create a large number of nested directories * Enforce a Landlock policy in which a rule is associated with each of these subdirectories * Benchmark openat() applied to the deepest directory, forcing Landlock to walk the entire path.
