└─>Verity target support
In linux kernel since version 3.1 (release Date: 2011-10-24)  
This device-mapper target creates a read-only device that
transparently validates the data on one underlying device against
a pre-generated tree of cryptographic checksums stored on a second

You'll need to activate the digests you're going to use in the
cryptoapi configuration.

To compile this code as a module, choose M here: the module will
be called dm-verity.

If unsure, say N.
