| H A D | errno.h | diff 104602 Mon Oct 07 04:25:26 MDT 2002 phk Copyin and copyout are only possible from a process-native thread, and therefore we need a way for ioctl handlers to run in that thread in GEOM. Rather than invent a complicated registration system to recognize which ioctl handler to use for a given ioctl, we still schedule all ioctls down the tree as bio transactions but add a special return code that means "call me directly" and have the geom_dev layer do that. Use this for all ioctls that make it as far as a diskdriver to avoid any backwards compatibility problems. Requested by: scottl Sponsored by: DARPA & NAI Labs |
