This patch carries forward a work-around from tcm_loop to target core code to explicitly clear control CDB READ paylods in order to avoid bugs in scsi-generic user-space code for INQUIRY that do not explicitly zero CDB payload memory. (v2: Drop TARGET_SCF_MAP_CLEAR_MEM, and perform the explicit zero of READ memory for all target_submit_cmd_map_sgls users) Cc: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
