Test covers inotify, fanotify, f_fsid, libblkid, IMA, exportfs file handles and libblkid tools verify with metadata_uuid. New helpers: _loop_image_create_clone() and _loop_image_destroy() to help create fs and clone _clone_mount_option() helper to apply per-filesystem clone mount options _require_fanotify_function check if kernel supports fs notification _require_unique_f_fsid() helper to handle fs difference in fsid implementation New tests: - fanotify events are isolated between cloned filesystems - f_fsid is unique across cloned filesystem instances - libblkid correctly resolves duplicate UUIDs to distinct devices with and without metadata_uuid - IMA distinct identity for each cloned filesystem - exportfs file handles resolve correctly on cloned filesystems Kernel Patches: Requires Btrfs kernel patches for all tests to pass.
