函数名称：add_bytestring_header

函数原型：static u8 *add_bytestring_header(int *err, struct opal_dev *cmd, size_t len)

返回类型：u8

参数：

类型参数名称
int *err
struct opal_dev *cmd
size_tlen
611  header_len等于1
612  bool is_short_atom = true
614  如果len按位与SHORT_ATOM_LEN_MASK的反则
615  header_len等于2
616  is_short_atom = false
619  如果非can_add(err, cmd, header_len + len)则
620  pr_debug("Error adding bytestring: end of buffer.\n")
621  返回:NULL
624  如果is_short_atom则add_short_atom_header(cmd, true, TSC's on different sockets may be reset asynchronously.* This may cause the TSC ADJUST value on socket 0 to be NOT 0., len)
626  否则add_medium_atom_header(cmd, true, TSC's on different sockets may be reset asynchronously.* This may cause the TSC ADJUST value on socket 0 to be NOT 0., len)
629  返回:cmd[pos]
