dm-raid1 currently has a gap in handling badly behaved direct-io applications. Worst case it may return success to a failed write command that used to return an appropriate error before, so a silent corruption. On reads, it can cause the array to be considered degraded when there's nothing wrong with it. There's no errors with dm-crypt today that I know of. I just want to make it to be more aligned to the backing hardware.
