We are trying to make a loadable pseudo-device driver. The problem seems to be that the "struct vdldrv" contains a pointer to an mb_device struct which is nonsense for a pseudo-device. We made it NULL, but the driver crashes in a walk_slave routine that suggests that that doesn't work. The comments in the example of the loadable device driver from Sun also do not talk about setting this to NULL. Has anyone succesfully created a loadable device driver for a pseudo device? We are running 4.1.1 if it is important. Sample drivers are appreciated. Hans van Staveren
