I went through Keith's v6.18/v6.19 series -- the block-size alignment
infrastructure is there (20a0e6276edb and surrounding), but I didn't
find a commit that actually wires cache-line alignment as the
requirement for non-coherent DIO (no dma_get_cache_alignment() or
L1_CACHE_BYTES references under block/ or drivers/nvme/ in that
range). If that enforcement is still future work building on Keith's
infrastructure, it's orthogonal to this patch's coherent-arch
suppression.
