hinge on the "verb" parameter which the class gets to interpret as

Move the entire request into the kernel and move changed parameters
back when done.

Introduce a init and fini member functions on a class.

Use ->init() and ->fini() to handle the mutex in geom_disk.c

Remove the g_add_class() function and replace it with a standardized
g_modevent() function.

This adds the basic infrastructure for loading/unloading GEOM classes

Remove the G_CLASS_INITIALIZER, we do not need it anymore.

Add gctl_set_param() function.

Rework the "withering" mechanism:

Introduce g_wither_geom() to do the work in one single place.

Remove the now obsolete geomidorname hack.

Introduce a g_waitfor_event() function which posts an event and waits for
it to be run (or cancelled) and use this instead of home-rolled versions.

Rename g_call_me() to g_post_event(), and give it a flag
argument to determine if we can M_WAITOK in malloc.

Make gctl_error() take printfline varargs.

Remove unused event pointers in object structures.
Remove KASSERTS which checked that they were unused.

Implement handling of CONFIG_GEOM OAM request.

Time has run from the "run GEOM in userland" harness, and the new regression
test is built to test GEOM as running in the kernel.

This commit is basically "unifdef -D_KERNEL" to remove the mainly #include
related code to support the userland-harness.

Remove all references to BIO_SETATTR. We will not be using it.

Remove geom_enc.c, a superset of these functions are now available in
<sys/endian.h>

Add handling for cancelled events in the g_call_me() methods.

Change events to have an array of "void *" references, and give the
event posting functions varargs to fill these.

Attribute g_call_me() to appropriate g_geom's where necessary.

Add a flag argument

Change events to have an array of "void *" references, and give the
event posting functions varargs to fill these.

Attribute g_call_me() to appropriate g_geom's where necessary.

Add a flag argument to g_call_me() methods which will be used to signal
cancellation of events in the future.

This commit should be a no-op.

Remove the old config interface, the new OAM is sufficiently functional
now.

Run a revision on the OAM api.

Use prefix gctl_ systematically.
Add flag with access perms for each argument.
Add ro/rw versions of argument building functions.
General cleanup.

Remove unuse g_insert_geom().

Premptively change initializations of struct g_class to use C99
sparse struct initializations before we extend the struct with
new OAM related member functions.

Retire the GEOM private statistics code and use devstat instead.

Add u_int nstart, nend counters to consumer and providers so we will not
have to examine the stats structure to tell if we have outstanding I/O
requests.

Add u_int nstart, nend counters to consumer and providers so we will not
have to examine the stats structure to tell if we have outstanding I/O
requests.

Making them u_int improves the chance of atomic updates to them,
but risks roll-over. Since the only interesting property is if
they are equal or not, this is not an issue.
