Yeah. Then again atomic writes in the traditional sense don't really make sense for zoned devices anyway as the zoned devices never overwrite and require all data up to the write pointer to be valid. In theory they could be interpreted so that you don't get a partical write failure if you stick to the atomic write boundaries, but that is mostly pointless.
