Remove 'vinum_perror'. Only call make_devices if we're not running devfs. Use userland expurgated versions of kernel structures, since that's what the ioctls return now. Update help list, which was lagging behind reality. checkupdates: move to list.c to simplify header file mess. vinum_stripe, vinum_mirror, vinum_raid4, vinum_raid5: change the default stripe size from 256 k to 279 k, thus hopefully spreading superblocks more evenly.
