This patch moves the blk_integrity_payload definition outside the CONFIG_BLK_DEV_INTERITY dependency and provides empty function implementations when the kernel configuration disables integrity extensions. This simplifies drivers that make use of these to map user data so they don't need to repeat the same configuration checks. Signed-off-by: Keith Busch <keith.busch@intel.com> Updated by Jens to pass an error pointer return from bio_integrity_alloc(), otherwise if CONFIG_BLK_DEV_INTEGRITY isn't set, we return a weird ENOMEM from __nvme_submit_user_cmd() if a meta buffer is set.
