524  pos等于0
526  buf等于'\0'
528  如果flags按位与_DPRINTK_FLAGS_INCL_TID则
529  如果in_interrupt()则pos加等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
531  否则pos加等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
535  pos_after_tid等于pos
536  如果flags按位与_DPRINTK_FLAGS_INCL_MODNAME则pos加等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
539  如果flags按位与_DPRINTK_FLAGS_INCL_FUNCNAME则pos加等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
542  如果flags按位与_DPRINTK_FLAGS_INCL_LINENO则pos加等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
545  如果pos减pos_after_tid则pos加等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
