Also the test for EOPNOTSUPP looks a bit fragile to me. Currently TST_FD_MEMFD is the only fd type where we'd get as far as checking whether the fs actually supports reflink but that could change in the future. So I'd not special-case MEMFD and instead add EOPNOTSUPP as another allowed error code. Otherwise the test looks good to me. Honza
