Raw Normal View History

[Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.] Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows. Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible. The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.

Phase 2 of the RAIDframe cleanup. The source is now closer to KNF and is much easier to read. No functionality changes.

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.

#include "rf_archs.h"
Get recent changes into the tree: - make component_label variables more consistent (==> clabel) - re-work incorrect component configuration code - re-work disk configuration code - cleanup initial configuration of raidPtr info - add auto-detection of components and RAID sets (Disabled, for now) - allow / on RAID sets (Disabled, for now) - rename "config_disk_queue" to "rf_ConfigureDiskQueue" and properly prototype in rf_diskqueue.h - protect some headers with #if _KERNEL (XXX this needs to be fixed properly) and cleanup header formatting. - expand the component labels (yes, they should be backward/forward compatible) - other bits and pieces (some function names are still bogus, and will get changed soon)
