crashes, the config remains locked and causes all
subsequent start or read attempts to fail. This is part
of a fix for the recently reported hangs.

vinum_read:
Accept 0 parameters, hand an empty string to the kernel if so.
Use new ioctl VINUM_READCONFIG, not VINUM_CREATE, to read config.
vinum_start: When passed 0 parameters, drop the devstat kludge and
call vinum_read instead. It's no longer necessary to distinguish
between "start" and "read" if no parameters are passed, and
probably one of them should go away.
Change name of history file to History to avoid name conflicts.
Don't try to make devices unless devfs has been removed.
Don't accept resetconfig command from a file.

Remove dead code (#if 0)
vinum_mirror: Don't try to create mirrors with 0 drives.
Found by: mismatch between enum kw in two different files.
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.
userland tool:
Use the vfs.devfs.generation sysctl to test for devfs presense
(thanks phk!) when devfs is active it will not try to create the
device nodes in /dev and therefore will not complain about the
failure to do so.
Revert the change in the #define for VINUM_DIR in the kernel
header so that vinum can find its device nodes.
Replace perror() with vinum_perror() to print file/line when
DEVBUG is defined (not defined by default).
kernel:
Don't use the #define names for the "superdev" creation since
they will be prepended by "/dev/" (based on VINUM_DIR), instead
use string constants.
Create both debug and non-debug "superdev" nodes in the devfs.

Add -i option to delay between blocks copied, to reduce performance
impact.
Remove -v option, things work now.
Rewrite parity maintenance functions.
Rebuildparity: Add -v option to check whether it was broken before
rebuilding each block.
enabled and print a warning message in varous places if they are not.
Fix typos in comments.
Change some indents to approach style(9).
initvol: If init fails, place the subdisks in a "down" state.
vinum_start(): If we're starting a plex, try doing it directly. It's
possible that the state of the plex differs from that of the subdisks,
for example if somebody has used 'setupstate'.
New functions vinum_raid4 and vinum_raid5 to create RAID-4 and RAID-5
volumes, analagous to vinum_mirror and vinum_stripe.
vinum_checkparity: Don't try to check the parity of a non-parity plex,
print a rude remark instead.

Add function vinum_mv, which moves subdisks to different drives. This
function just does the low-level configuration changes; the resultant
subdisk is stale if it previously had any contents, otherwise it is
empty (i.e. in need of initializing if it's RAID-5). We still need to
handle getting the contents moved over, but the current version will
suffice to migrate subdisks from a disk which has failed.

vinum_start: Get the revive block size right.

initsd: rewrite:
Initialization is now done in the kernel.
Verify (again!) if -v is specified.
Allow specification of a blocksize, the length to be transferred in
one transfer.
vinum_revive:
Allow specification of a blocksize, the length to be transferred in
one transfer.
vinum_start: bzero the statinfo.dinfo struct. The lack of this was
causing sporadic failures of the start command.
Add body of vinum_checkparity command.
vinum_init(): Change name of variable plexindex to objindex, which
better describes its purpose.
initsd(): Add a second parameter to determine whether it should wait
for completion or not. This allows it to DTRT when called
with the -w flag either directly or via initplex().
Add 'setstate' command (function vinum_setstate ()) to implement the
VINUM_SETSTATE_FORCE ioctl for diddling individual object states.
This is a repair tool which can also be used for panicing the system.
Use with utmost care if at all.
Add unimplemented commands 'checkparity' and 'rebuildparity'. Watch
this space.

Don't set the plex up, it should go up automatically.

vinum_stop: sleep for a second before unloading. This solves a race

When creating a new drive, if the drive already has a vinum label,

'force' flag is specified.

Rebuild the (almost empty) /dev/vinum directory.
vinum_start: remove superflous "read" parameter when starting with no

vinum_stop: without an argument, stop Vinum and remove the kld if

vinum_saveconfig: New command to save configuration.
