    This patch converts a handful of iscsi_session statistics to type
    atomic_long_t, instead of using iscsi_session->session_stats_lock
    when incrementing these values.
    
    More importantly, go ahead and drop the spinlock usage within
    iscsit_setup_scsi_cmd(), iscsit_check_dataout_hdr(),
    iscsit_send_datain(), and iscsit_build_rsp_pdu() fast-path code.
    
    (Squash in Roland's  target: Remove write-only stats fields and lock
    from struct se_node_acl)
