This is a fabrics target you're talking about? I assume so because pci would use PRP for a 4k payload, which doesn't encode transfer lengths. All the offending controllers were pci, so maybe we could have constrained the DSM over-allocation to that transport if we knew this was causing problems for fabrics.
