This patch adds blk_integrity passthrough support for block_device backends using IBLOCK. This includes iblock_alloc_bip() + setup of bio_integrity_payload information that attaches to the leading struct bio once bio_list is populated during fast-path iblock_execute_rw() I/O dispatch. It also updates setup in iblock_configure_device() to detect modes of protection + se dev->dev_attrib.pi_prot_type accordingly, along with creating required bio_set integrity mempools. Cc: Martin K.
