v6: . Renamed `pre_clone_tune_uuid()` to `_change_metadata_uuid()`. . Created the `_require_unique_f_fsid()` helper instead of handling it inside the test case (patch 5/11). . Separated `FSNOTIFYWAIT_PROG` into its own patch. . Dropped the `inotify` test case in favor of `fsnotify`. . Added comments throughout, especially for helper functions.
v5: https://lore.kernel.org/fstests/[email protected] v4: https://lore.kernel.org/fstests/[email protected] v3: https://lore.kernel.org/fstests/[email protected] v2: https://lore.kernel.org/fstests/[email protected] v1: https://lore.kernel.org/fstests/[email protected] This series adds fstests infrastructure and test cases to verify correct filesystem identity when a filesystem is cloned (block-level copy). 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 _change_metadata_uuid() changes the UUID before the clone 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.
