You need your kernel and ccdconfig(8) to be in sync, particularly if your
source tree is on a ccd device.

Change the list interface to simplify things.
Remove old list ioctls which bogusly exported the softc to userland.
Move the softc and associated structures from the public header to
the source file.

Make CCD a GEOM class.
For now only use this for implementing a OAM config method which
can return a list of configured CCD devices in the format which
"ccdconfig -g[v]" would normally output.

Retain the mistake of not updating the devstat API for now.
Spell bioq_disksort() consistently with the remaining bioq_*().
#include <geom/geom_disk.h> where this is more appropriate.

As a side effect this makes a lot of #include <sys/devicestat.h>
lines not needed and some biofinish() calls can be reduced to
biodone() again.

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.
This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

Change the argument to disk_destroy() to be the same struct disk * as
disk_create() takes.
This enables drivers to ignore the (now) bogus dev_t which disk_create()
returns.

CAUTION:
Previously CCD would be different from all other disks in
the system in that there were no "ccd0" device, only a
"ccd0c" device.
This is no longer so after this commit. If you access a
ccd device through the "/dev/ccd0c" device _and_ have not
actually put a BSD disklabel on the device, you will have
to use the name "/dev/ccd0". If your CCD device contains
a BSD disklabel there should be no difference.
You need to recompile ccdconfig(8) using the changed
src/sys/sys/ccdvar.h for the -g "show me" option to work.
I have run the regression test I created before I started
overhauling CCD and it flags no problems, but this code
is mildly evil, so take care. If you would cry if you lost
what's on CCD, make a back before you upgrade.
Create separate cdevsw for the /dev/ccd.ctl device.
Remove the cloning function, the disk-minilayer will do all naming
for us.
Remove the ccdunit and ccdpart functions and carry the softc pointer
in the relevant dev_t's and structures.
Release all memory when a CCD device is unconfigured, previously
the softc would linger behind.
Remove all traces of BSD disklabel fiddling code.
Remove ccdpsize, the disk mini-layer does this for us.
Don't allocate memory with M_WAITOK in ccdstrategy().
Remove boundary checks which the disk mini-layer does for us.
Don't allocate space for more than 2 ccdbuf, RAID was never implemented.
NB: I have not tried to address any of the preexisting ailments of CCD.

These two compatibility measures will be retained only for a limited

and predictable way, and I apologize if I have gotten it wrong anywhere,
getting prior review on a patch like this is not feasible, considering
the number of people involved and hardware availability etc.)
If struct disklabel is the messenger: kill the messenger.
Inside struct disk we had a struct disklabel which disk drivers used to
communicate certain metrics to the disklayer above (GEOM or the disk
mini-layer). This commit changes this communication to use four
explicit fields instead.
Amongst the benefits is that the fields do not get overwritten by
wrong or bogus on-disk disklabels.
Once that is clear, <sys/disk.h> which is included in the drivers
no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in,
the few places that needs them, have gotten explicit #includes for
them.
The disklabel inside struct disk is now only for internal use in
the disk mini-layer, so instead of embedding it, we malloc it as
we need it.
This concludes (modulus any mistakes) the series of disklabel related
commits.
I belive it all amounts to a NOP for all the rest of you :-)

Printing daddr_t's using %d format was always an error, but gcc's
warning about it was ignored for supported 64-bit arches and not printed
for supported 32-bit arches. Hundreds if not thousands thousands of
previously "fixed" daddr_t printings are now broken on 32-bit machines
by casting daddr_t's to longs. daddr_t's should be printed using %jd
format, but this fix uses %lld since %j is not implemented in the
kernel yet.
Fixed some nearby format printf errors (style bugs).

the bio and buffer structures to have daddr64_t bio_pblkno,
b_blkno, and b_lblkno fields which allows access to disks
larger than a Terabyte in size. This change also requires
that the VOP_BMAP vnode operation accept and return daddr64_t
blocks. This delta should not affect system operation in
any way. It merely sets up the necessary interfaces to allow
the development of disk drivers that work with these larger
disk block addresses. It also allows for the development of
UFS2 which will use 64-bit block addresses.

This is functionally equivalent to teh previousl -current except
