aa258f8f85 Use KTR to log allocations and destructions of bios. 
This should hopefully allow to track down "duplicate free of g_bio" panics.

bd2fb8891e Prevent that sync operations can be started when they are already 
in progress, and be a bit more user friendly in terms of error

33712bde29 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.

a2f0d0b06b 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.

e3eb852545 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.

other file system exist in /etc/fstab which are placed on RAID3 device,
boot process will be interrupted when these devices are missing.

388b4d6c8d 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.

da0fa3b3e0 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.
