Is this true? Are there compatibility issues using different i/o schedulers with software raid?

I'd actually like to raise this one level further:

In the case of (drives)->md->dm(crypto)->lvm->fs, how do the schedulers, readahead settings, blocksizes, barriers etc interact thru all these layers? Is block caching done on all layers? Is readahead done on all layers?
