3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx> commit 01c681d4c70d64cb72142a2823f27c4146a02e63 upstream. The 'handle' is the device that the request is from. For the life-time of the ring we copy it from a request to a response so that the frontend is not surprised by it. But we do not need it - when we start processing I/Os we have our own 'struct phys_req' which has only most essential information about the request. In fact the 'vbd_translate' ends up over-writing the preq.dev with a value from the backend. This assignment of preq.dev with the 'handle' value is superfluous so lets not do it.
