  1095	 * registry_list_entry - linked list member for a registry key/value
  1096	 * @head: list_head struct
  1097	 * @type: dword, binary, or string
  1098	 * @klen: the length of name of the key
  1099	 * @vlen: the length of the value
  1100	 * @key: the key name
  1101	 * @dword: the data, if REGISTRY_TABLE_ENTRY_TYPE_DWORD
  1102	 * @binary: the data, if TYPE_BINARY or TYPE_STRING
  1103	 *
  1104	 * Every registry key/value is represented internally by this struct.
  1105	 *
  1106	 * Type DWORD is a simple 32-bit unsigned integer, and its value is stored in
  1107	 * @dword.
  1108	 *
  1109	 * Types BINARY and STRING are variable-length binary blobs.  The only real
  1110	 * difference between BINARY and STRING is that STRING is null-terminated and
  1111	 * is expected to contain only printable characters.
  1112	 *
  1113	 * Note: it is technically possible to have multiple keys with the same name
  1114	 * but different types, but this is not useful since GSP-RM expects keys to
  1115	 * have only one specific type.
