From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx> This patch adds READ_INSERT support in target_check_read_prot() that invokes sbc_dif_generate() when LIO is responsible for generating the outgoing T10-PI. Required for supporting fabrics that exchange protection information, and would like to function with un-protected devices.
