fcac1be89a Set the G_PF_WITHER flag on the subdisk provider that is about to 
be destroyed.  That way the GEOM system handles all deallocations
and we don't have to do it ourselves.

e4da09c03f Remove a race condition that could result in processes being stuck 
waiting for geom events to happen:

Instead of maintaining a count of outstanding events, simply look if
the queue is empty.  Make sure to not remove events from the queue
until they are executed in order to not open a new race.

df5175af0f Shuffle around the order in which the components are compiled. 
This way, the VINUMDRIVE class is loaded before the VINUM class,
but since geom does the tasting for newly arrived classes
last-in-first-out, the VINUM class tastes first.

This removes the need to call gv_parse_config() in the drive
taste path.

efd9ac0dfc Add a __packed keyword to g_eli_metadata struct definition, so 
sizeof(struct g_eli_metadata) will return the exact number of bytes needed
for storing it on the disk.
Without this change GELI was unusable on amd64 (and probably other 64-bit
archs), because sizeof(struct g_eli_metadata) was greater than 512 bytes
and geli(8) was failing on assertion.

8cc5eb98ad Fix a stupid logic bug introduced in geom_vinum_drive.c rev 1.18: 
When a drive is newly created, it's state is initially set to 'down',
so it won't allow saving the config to it (thus it will never know of
itself being created).  Work around this by adding a new flag, that's
also checked when saving the config to a drive.

8827c821de By design I left a tiny race in updating the I/O statistics based on 
the assumption that performance was more important that beancounter
quality statistics.

As it transpires the microoptimization is not measurable in the
real world and the inconsistent statistics confuse users, so revert
the decision.

565bc10111 Add a very simple and small GEOM class - ZERO. 
It creates very huge provider (41PB) /dev/gzero.
On BIO_READ request it zero-fills bio_data and on BIO_WRITE it does nothing.
You can also set kern.geom.zero.clear sysctl to 0 to do nothing even for
BIO_READ.

I'm using it for performance testing where it is very helpful.
