As the new approach, as I mentioned above, will defer the detach to last close and the last close happens *only* when the LTP test function tst_detach_device_by_fd() returns, the test will obviously fail. So, Can you please modify the LTP test case to accommodate the new behaviour of kernel code for loop detach?

I still think simply setting the rundown state is the better approach..
