- This is the integrity target.
+ This device-mapper target emulates a block device that has additional
+ per-sector tags that can be used for storing integrity information.
+ The dm-integrity target is used with the dm-crypt target to provide
+ authenticated disk encryption or it can also be used as a standalone
+ target. In standalone mode it calculates and verifies the data integrity
+ internally.
+ You should enable this option if you plan to use dm-crypt target
+ in authenticated disk encryption mode.
+ To compile this code as a module, choose M here: the module will
+ be called dm-integrity.
+ If unsure, say N.
