Hi, When I was testing ioctls on missing backing devices for loop devices I found an anomaly in how the system reports it and I wonder if it is by design or a bug. A missing backing device for a loop device will still respond favourably to the LOOP_GET_STATUS ioctl while inactive devices respond with ENODEV. However when the backing device has been absent for a great while (at least multiple hours) the response turns into EIO. This is kernel 4.10 btw. So to make it more clear: - loop device not in use at all = ENODEV - loop device "gone" = 0 - loop device "gone" after multiple hours = EIO. And I wonder if this change from 0 to EIO is by design or not?
