Looks good to me. Some minor issues inline.

Thanks for the test!

We have _require_test_program helper now, just
_require_test_program "t_immutable"

Seems _filter_scratch is not needed.

Run the t_immutable test program for immutable/append-only files
and directories in an overlayfs upper directory.
This test is similar and was derived from generic/079, but
the original test is _notrun on overlay mount because FS_IOC_GETFLAGS
FS_IOC_SETFLAGS ioctls fail on overlay directory inodes.

Eryu,
Here is v2 with fixes to your comments.
I also changed generic/079 to use modern _require_* statements.
and removed _scratch_unmount from its cleanup callback.
Amir.
