Hi Peter, Regardless if we rip out the entire rule of majors for dev_t, will there be a service dummy driver to various block-devices? There is a real need for this if we are going to get full control of the hardware by indirect access obtain the functionality that I see and need in the near future. I want to use KMOD to an advantage. Assume removable device bays such that you can swap in any and every kind of ata-atapi device and/or all scsi-devices, one needs to have a way to tell the driver to do things that are not native to its general mode of operations as of today.
