Yes, sorry, this is our oversight. Mike already promised that this text will be extended in the next patchset. For now you can find the description in documentation Documentation/device-mapper/dm-integrity.txt "The dm-integrity target emulates a block device that has additional per-sector tags that can be used for storing integrity information." (The major designed use case is for providing metadata space for tags for authenticated encryption in dm-crypt but it can be used also as a standalone target.)
