Hi, The extended query device verb was pulled out of kernel v3.19 at the last moment because of needed changes in the ABI it will expose. This patch-set re-introduces the verb, with the changes proposed by Yann Droneaud [1], and also returning the response length as part of the response, as suggested by Ira Weiny [2]. I hope it can be accepted into v3.20.
