  22 /*
  23  * The 'FIELD' macro arguments are defined as follows:
  24  * 1. report_type.  An enum value that selects a specific
  25  * struct dm_report_object_type in the _report_types array.  The value is
  26  * used to select the containing base object address (see *obj_get*
  27  * functions) for any data values of any field in the report.
  28  * 2. Containing struct.  The structure that either contains the field data
  29  * as a member or should be used to obtain the field data.  The containing
  30  * struct should match the base object of the report_type.
  31  * 3. Field type.  This must be either 'STR' or 'NUM'.
  32  * 4. Report heading.  This is the field heading that is displayed by the
  33  * reporting commands.
  34  * 5. Data value pointer.  This argument is always a member of the
  35  * containing struct.  It may point directly to the data value (for example,
  36  * lv_uuid - see _uuid_disp()) or may be used to derive the data value (for
  37  * example, seg_count - see _lvsegcount_disp()).  In the FIELD macro
  38  * definition, it is used in an offset calculation to derive the offset to
  39  * the data value from the containing struct base address.  Note that in some
  40  * cases, the argument is the first member of the struct, in which case the
  41  * data value pointer points to the start of the struct itself (for example,
  42  * 'lvid' field of struct 'lv').
  43  * 6. Minimum display width.  This is the minimum width used to display
  44  * the field value, typically matching the width of the column heading.
  45  * 7. Display function identifier.  Used to derive the full name of the
  46  * function that displays this field.  Derivation is done by appending '_'
  47  * then prepending this argument to '_disp'.  For example, if this argument
  48  * is 'uuid', the display function is _uuid_disp().  Adding a new field may
  49  * require defining a new display function (for example _myfieldname_disp()),
  50  * or re-use of an existing one (for example, _uint32_disp()).
  51  * 8. Unique format identifier / field id.  This name must be unique and is
  52  * used to select fields via '-o' in the reporting commands (pvs/vgs/lvs).
  53  * The string used to specify the field - the 'id' member of
  54  * struct dm_report_field_type.
  55  * 9. Description of field.  This is a brief (ideally <= 52 chars) description
  56  * of the field used in the reporting commands.
