If it is a simple and compatible change it sounds very good. I haven't looked into it enough to claim it'll be a simple change. I figure the iscsi recv code will change completely, but would be simplified as we don't need to deal with the tcp buffer details etc. when using a simple socket recv call, but it remains to be seen how this affects compatibility, i.e. conc. partial or interrupted transfer. It is not decided whether we allocate resources for this.
