The ioctl has a version field:
struct dm_ioctl { uint32_t version[3]; ...
and the above patch changes version 1.6.0 into 2.0.0. With sufficiently recent user space utilities all should work: they can find out the interface version using the DM_VERSION ioctl, and then adapt what they send to the kernel. (I don't know whether such up-to-date utilities exist.)
