92f49a969d If we kill the worklist thread of a RAID5 plex we can destroy 
the worklist mutex at the same time, so move the mtx_destroy() call
to gv_kill_thread().

663e5a3311 Set the access counts of a subdisk correctly when attaching it 
to a plex that already has subdisks.

07c424cdaf Shut up the compiler and temporarily '#if 0' gv_destroy_geom(), 
until we need it again.

3242376072 There's a chance that the VINUMDRIVE class tastes before the 
VINUM class, so let the VINUMDRIVE class parse the on-disk
configuration, too.

c291a77678 Use a temporary geom when tasting vinumdrives and lock the 'real' 
vinumdrive geom with an exclusive bit.  This should fix the problem
when underlying partitions overlap (i.e. the 'a' partition is at
the same offset as the 'c' partition).

Ideas borrowed from pjd@, quite a bit of testing by
Matthias Schuendehuette <msch@snafu.de>.

how to do it correctly.

865897c9f1 Mark a plex as 'newborn' when it is created. This is used to indicate 
that new RAID5 plexes need to be initialized first.

d7af790b0d 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.

finished or when building the complete packet fails.

a6facf72b1 Don't free a VINUMDRIVE softc when it's orphaned or spoiled. All 
allocated ressouces should be ultimately freed in gv_destroy_geom()
(when unloading the module and not earlier), but I need to look at this
more closely.
