5 The dm-integrity target emulates a block device that has additional
6 per-sector tags that can be used for storing integrity information.
9 writing the sector and the integrity tag must be atomic - i.e. in case of
10 crash, either both sector and integrity tag or none of them is written.
12 To guarantee write atomicity, the dm-integrity target uses journal, it
13 writes sector data and integrity tags into a journal, commits the journal
14 and then copies the data and integrity tags to their respective location.
16 The dm-integrity target can be used with the dm-crypt target - in this
17 situation the dm-crypt target creates the integrity data and passes them
