90094c67a1 Introduce some serious paranoia to try to catch a memory overwrite problem 
as early as possible.

4509f96cc5 Make kernel dumps work with GEOM. 
Notice that if the device on which the dump is set is destroyed for
any reason, the dump setting is lost.  This in particular will
happen in the case of spoilage.  For instance if you set dump on
ad0s1b and open ad0 for writing, ad0s* will be spoilt and the dump
setting lost.  See geom(4) for more about spoiling.

a90e28ebbb Implement DIOCGFRONTSTUFF ioctl which reports how many bytes from the start 
of the device magic stuff might occupy.

e11a1be17e In the absense of any smarter way to do this, cast various printf 
arguments to silence printf format warnings.

aeded84143 Eliminate some thread pointers which do not make sense anymore. 
Split private parts of geom.h into geom_int.h.  The latter should
never be included in class implemtations.

1af8cfb2f2 Cave in to tradition and rename "methods" to "classes". 2002-03-26 21:40:06 +00:00

093fe76cad Forgot to remove the old g_malloc() call when I split it.

3e53a43775 First commit of the GEOM subsystem to make it easier for people to 
test and play with this.

This is not yet production quality and should be run only on dedicated
test boxes.

For people who want to develop transformations for GEOM there exist a
set of shims to run geom in userland (ask phk@freebsd.org).

Reports of all kinds to: phk@freebsd.org
Please include in report:
        dmesg
        sysctl debug.geomdot
        sysctl debug.geomconf

Known significant limitations:
        no kernel dump facility.
        ioctls severely restricted.
