Step 2 of the disentanglement. We now look to <dev/raidframe/*> for the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h, rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places. Believe it or not, when this is all done, things will be cleaner. No functional changes to RAIDframe.

/* $NetBSD: rf_dagdegrd.h,v 1.4 2001/10/04 15:58:52 oster Exp $ */
RAIDframe, version 1.1, from the Parallel Data Laboratory at Carnegie Mellon University. Full RAID implementation, including levels 0, 1, 4, 5, 6, parity logging, and a few other goodies. Ported to NetBSD by Greg Oster.

/* degraded read DAG creation routines */
Phase 2 of the RAIDframe cleanup. The source is now closer to KNF and is much easier to read. No functionality changes.
