 /*
  * Offsets of . and .. in data space (always block 0)
  *
- * The macros are used for shortform directories as they have no headers to read
- * the magic number out of. Shortform directories need to know the size of the
- * data block header because the sfe embeds the block offset of the entry into
- * it so that it doesn't change when format conversion occurs. Bad Things Happen
- * if we don't follow this rule.
- *
  * XXX: there is scope for significant optimisation of the logic here. Right
  * now we are checking for "dir3 format" over and over again. Ideally we should
  * only do it once for each operation.
