the three configuration ioctls which need a unit number.
Add a "ccd.ctl" device for config operations.
Implement ioctls on ccd.ctl which rely on the explicityly passed
unit numbers.
Update ccdconfig to use the new ccd.ctl interface.
Add code to the kernel to detect old ccdconfig binaries, and whine
about it.
Add code to ccdconfig to detect old kernels, and whine about it.
These two compatibility measures will be retained only for a limited
period since they are in the way of GEOM'ification of ccd.
descriptor request, which usbd_get_string_desc() uses to get the
length of a descriptor. One device for instance returns a full 8
byte long packet instead which confuses the rest of the stack and
leads to the USB port being reset. The fix is to instead request
two bytes, but not to complain if we only get one.

simplifies error exit cases as well. Also be sure to set errno
and clean up resources in !mac error case.

confuses the controller, tell CAM not to do it. Also report the
correct error condition to CAM when it tries to probe a target that
doesn't exists.
This should make the CAM interface less risky to use.

- Don't panic on contigmalloc failure.
- Calculate timestamp by feedforward rather than feedback which depends on
unreliable interrupt timing.
- Overwrite timestamp in CIP header correctly.
- Add debug code for timestamp synchronization.
- Add comments.
Only grab giant in the per unit kthread for SWAP and VNODE backed devices.
Initialize the bioq before the kthread gets a chance to study it.
Don't lock Giant in mddone_swap, we shouldn't need it.
inconsistent when we do not do it for swap or vnode.
We still printf for preloaded disks because of the weak debugging
options people have in embedded/tiny environments where this is
usually used.
pointer types, and remove a huge number of casts from code using it.
Change struct xfile xf_data to xun_data (ABI is still compatible).
If we need to add a #define for f_data and xf_data we can, but I don't
think it will be necessary. There are no operational changes in this
commit.
expectation.
This solves the problem, where in a constellation with two (or more)
drives, an attempt is made to access a device name for that device
using a historic partition letter, like /dev/fd1c. This is supposed
to create a symlink to the master device, but previously, the link was
always created to /dev/fd0, even if the request was for fd1*.
