I prefer high-performance drivers. There are enough other things (virt_to_bus, ioremap, et al) that are non-optional that driver writers must learn about for non-peecee driver programming that proper use of mb/wmb doesn't seem that big a deal to me. I guess I personally can afford to be somewhat idealistic in this, because I only use about 4 drivers -- ncr, aic7xxx, tulip, epic100 -- and the authors of all these drivers have clue. But the thought of coddling to folks that can't be bothered to do things Right gives me hives. r~ [[ This message was sent via the linuxppc-dev mailing list.
