You mean my SCSI cciss driver? For a few reasons: At the time, it was just kind of a learning exercise, and I didn't see it as supplanting the existing driver. I didn't know enough about udev to know that a smooth transition process was perhaps possible, and it seemed very disruptive. And, seeing as how I work for HP, it isn't exactly within my authority to just decide by myself the course the driver development should take. Paradoxically, if a person works for a company that has nothing to do with the driver, one has more freedom to do whatever one wants with the code. With help from udev it is less disruptive, but I'm still unsure about how smoothly such a change will fit in with the installation process of various distributions. I will see if management here will let me send you the patches from when I last looked at this, which was a little over a year ago. (2.6.20 timeframe), not necessarily to use as is, but in case maybe it helps to see how somebody else proceeded. As for the patches I mentioned which were previously ignored for improving how the current cciss SCSI code handled hot plogging, if you're curious about that, check here: http://marc.info/?l=linux-scsi&m=120213565000426&w=4 A change like that becomes more important if logical drives are exposed through the scsi layer. -- steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
