| Doc Text: |
Cause: "multipath -f <device>" was returning success if there was no work that needed to be done.
Consequence: If "multipath -f" was run on a non-existent or non-multipath device, it would return success, since there was no device to remove
Fix: multipath now returns failure when a remove is attempted on an invalid device.
Result: running "multipath -f" on a non-existent device now fails.
