Nick Hibma 540d9130cc Add a hack to cam that makes the cam_xpt available to the rest of the ... kernel. Justin agress that there is no other reasonable alternative to do automatic rescans on connect. The problem is that when a new device attaches to a SIM (SCSI host controller) we need to send a XPT_SCAN_BUS command to the SIM using xpt_action. This requires however that there is a peripheral available to take the command (otherwise xpt_done and later bomb). The RESCAN ioctl uses the same periph. This enables a USB mass storage drive to do an automatic rescan on connection of the drive. The automatic dropping of a CAM entry on disconnection was already working (asynchronous event). The next thing to do is find someone to commit a change to vpo to do the same thing. Just port umass_cam_rescan and friends across to that driver. Approved by: gibbs		2000-04-03 11:11:12 +00:00
