b14d84e24b Change the giant-dropping method a fair bit to keep WITNESS more 
happy.

14e4cefcf8 Hmm, talk about optimizer-fodder. Make the DIOCGDVIRGIN hack work again. 2002-03-16 13:47:57 +00:00

a5b2e75d32 Add a generic and general ioctl pass-through mechanism. 
It should now be posible to issue ioctls to SCSI CD drives.

dd84a43c1d 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.
