Hello all, Is there a technical reason that DATA_DEV_BLOCK_SIZE_MIN_SECTORS is limited to 64k? I realize that the metadata limits the maximum mappable pool size, so it needs to be bigger for big pools---but it is also the minimum COW size. Looking at the code this is enforced in pool_ctr() but isn't used anywhere else in the code. Is it strictly necessary to enforce this minimum?
