    target: Add protection SGLs to target_submit_cmd_map_sgls · def2b339
    Nicholas Bellinger authored
    This patch adds support to target_submit_cmd_map_sgls() for
    accepting 'sgl_prot' + 'sgl_prot_count' parameters for
    DIF protection information.
    
    Note the passed parameters are stored at se_cmd->t_prot_sg
    and se_cmd->t_prot_nents respectively.
    
    Also, update tcm_loop and vhost-scsi fabrics usage of
    target_submit_cmd_map_sgls() to take into account the
    new parameters.
