Christoph,
All our block I/O must be cache line aligned, so dword aligned SGLs should not be an issue. And for PRPs or MRs we'll always use the host page size.
Where is that constraint coming from? Is that new? Back when I wrote GAP support in rdma I tested a single byte alignment via vectored direct IO and it seemed to be going through... I also just tested Bart's unaligned test [1] on scsi_debug and it seems to go through as well (alignment and length are 4)...
