Closes: https://github.com/linux-test-project/ltp/issues/1175

> Since commit 18048c1af783 ("loop: Fix a race between loop detach and loop open")
> detach operation is deferred to the last close of the device.

> Make tst_detach_device_by_fd() also close dev_fd, and leave it up to
> caller to re-open it for further use.

6.11.0-rc3-2.g00af0c0-default

Kind regards,
Petr
