- 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.
+
+ This integrity target is used with the dm-crypt target to
+ provide authenticated disk encryption or it can be used
+ standalone.
+
+ To compile this code as a module, choose M here: the module will
+ be called dm-integrity.
