One good thing about ZFS integrity checking is that when it finds an error it can repair the bit rot from another disk if you have parity or mirroring. Can dm-integrity do that?
dm-integrity will only operate on a single disk so no, not on its own.
It does however return an error if the integrity check fails, so if you put mdadm on top, mdadm can repair the erroneous block. I've tested this and am currently running it on a 32TB array.
