Change events to have an array of "void *" references, and give the

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

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.

Introduce flag field and G_PF_CANDELETE field on providers.

Move the g_stat struct to its own .h file, we will export it to other code.

Insted of embedding a struct g_stat in consumers and providers, merely

Move the g_stat struct to its own .h file, we will export it to other code.

Insted of embedding a struct g_stat in consumers and providers, merely
include a pointer.

Remove a couple of <sys/time.h> includes now unneeded.

Add a special allocator for struct g_stat. This allocator will allocate
entire pages and hand out g_stat functions from there. The "id" field
indicates free/used status.

Add "/dev/geom.stats" device driver whic exports the pages from the
allocator to userland with mmap(2) in read-only mode.

This mmap(2) interface should be considered a non-public interface and
the functions in libgeom (not yet committed) should be used to access
the statistics data.

Commit the correct copy of the g_stat structure.

Add debug.sizeof.g_stat sysctl.

Set the id field of the g_stat when we create consumers and providers.

Remove biocount from consumer, we will use the counters in the g_stat
structure instead. Replace one field which will need to be atomically
manipulated with two fields which will not (stat.nop and stat.nend).

Change add companion field to bio_children: bio_inbed for the exact
same reason.

Don't output the biocount in the confdot output.

Fix KASSERT in g_io_request().

Add sysctl kern.geom.collectstats defaulting to off.

Collect the following raw statistics conditioned on this sysctl:

for each consumer and provider {
total number of operations started.
total number of operations completed.
time last operation completed.
sum of idle-time.
for each of BIO_READ, BIO_WRITE and BIO_DELETE {
number of operations completed.
number of bytes completed.
number of ENOMEM errors.
number of other errors.
sum of transaction time.
}
}

API for getting hold of these statistics data not included yet.

Add the new statistics structure, put one in consumers and providers.
include <sys/time.h> as necessary.

Use a void * to carry the private data for return-call'ed ioctl requests.
Amongst other things this avoids a complex workaround in the userland
regression bits.

Remove g_silence(). It does not do anything anymore.

Constification and some s/int/u_int/ changes.

Use more mnemonic argument names in the access functions.

Add a g_dev_print() function which prints all the /dev entries GEOM
know about.

Make the sectorsize a property of providers so we can include it in the XML
output.

Moved geom class initialization to SI_SUB_DRIVERS from SI_SUB_PSEUDO.
This fixes mounting root from md(4) which calls disk_create() early.

Implement the GEOMCONFIGGEOM ioctl which can be used to manually create
and configure an instance of a class on a give provider.
