3483cf5337 Don't force class to give a valid softc to g_slice_new(), it is not always 
needed.

7e172b8cb6 Currently, if the drives specified for volume creation are 
not active GEOM providers, it will result in a kernel panic.

If the GEOM provider or disk goes away before the volume
configuration data gets written to the disk, it will result
in another kernel panic.

o Make sure that the drives specified for volume creation
  are active GEOM providers.

o When writing out volume configuration data to associated drives,
  make sure that the GEOM provider is active, otherwise continue
  to the next drive in the volume.

40dd98a3bd Second half of the dev_t cleanup. 
The big lines are:
	NODEV -> NULL
	NOUDEV -> NODEV
	udev_t -> dev_t
	udev2dev() -> findcdev()

Various minor adjustments including handling of userland access to kernel
space struct cdev etc.

7429d59ed6 Don't free a VINUMDRIVE softc when it's orphaned or spoiled. All

Bit 0 controls statistics collection on GEOM providers.
Bit 1 controls statistics collection on GEOM consumers.

90c2eca016 Introduce NOP GEOM class. This is totally transparent GEOM class, but 
it is very useful for tests. One is able to destroy its provider
forcibly if wants to test how other class handle such events.
One is also able to specify failure probability to check how other
classes handle I/O errors.

9a7074f4cb Rearrange some of the GEOM debugging tools to be more structured. 
Retire g_sanity() and corresponding debugflag (0x8)

  Retire g_{stall,release}_events().

  Under #ifdef DIAGNOSTIC:

    Make g_valid_obj() an official function and have it return an an
    non-zero integer which indicates the kind of object when found.

    Implement G_VALID_{CLASS,GEOM,CONSUMER,PROVIDER}() macros based
    on g_valid_obj().

    Sprinkle calls to these macros liberally over the infrastructure.

    Always check that we do not free a live object.
