/* rf_archs.h -- defines for which architectures you want to
 * include is some particular build of raidframe.  Unfortunately,
 * it's difficult to exclude declustering, P+Q, and distributed
 * sparing because the code is intermixed with RAID5 code.  This
 * should be fixed.
 *
 * this is really intended only for use in the kernel, where I
 * am worried about the size of the object module.  At user level and
 * in the simulator, I don't really care that much, so all the
 * architectures can be compiled together.  Note that by itself, turning
 * off these defines does not affect the size of the executable; you
 * have to edit the makefile for that.
 *
 * comment out any line below to eliminate that architecture.
 * the list below includes all the modules that can be compiled
 * out.

 *
 * Revision 1.26  1996/06/17  14:38:33  jimz
 * properly #if out RF_DEMO code
 * fix bug in MakeConfig that was causing weird behavior
 * in configuration routines (config was not zeroed at start)
 * clean up genplot handling of stacks
 *
 * Revision 1.25  1996/06/14  21:24:59  jimz

 *
 * Revision 1.24  1996/06/13  20:41:57  jimz
 * add RF_INCLUDE_QUEUE_RANDOM (0)
 *
 * Revision 1.23  1996/06/11  18:12:36  jimz
 * get rid of JOIN operations
 * use ThreadGroup stuff instead
 * fix some allocation/deallocation and sync bugs
 *
 * Revision 1.22  1996/06/10  22:24:55  wvcii

 *
 * Revision 1.21  1996/06/05  18:06:02  jimz
 * Major code cleanup. The Great Renaming is now done.
 * Better modularity. Better typing. Fixed a bunch of
 * synchronization bugs. Made a lot of global stuff
 * per-desc or per-array. Removed dead code.
 *
 * Revision 1.20  1996/05/30  11:29:41  jimz
 * Numerous bug fixes. Stripe lock release code disagreed with the taking code
 * about when stripes should be locked (I made it consistent: no parity, no lock)
 * There was a lot of extra serialization of I/Os which I've removed- a lot of
 * it was to calculate values for the cache code, which is no longer with us.
 * More types, function, macro cleanup. Added code to properly quiesce the array
 * on shutdown. Made a lot of stuff array-specific which was (bogusly) general
 * before. Fixed memory allocation, freeing bugs.
 *
 * Revision 1.19  1996/05/27  18:56:37  jimz
 * more code cleanup
 * better typing
 * compiles in all 3 environments
 *
 * Revision 1.18  1996/05/23  21:46:35  jimz
 * checkpoint in code cleanup (release prep)
 * lots of types, function names have been fixed
 *
 * Revision 1.17  1996/05/23  00:33:23  jimz
 * code cleanup: move all debug decls to rf_options.c, all extern
 * debug decls to rf_options.h, all debug vars preceded by rf_
 *
 * Revision 1.16  1996/05/18  19:51:34  jimz
 * major code cleanup- fix syntax, make some types consistent,
 * add prototypes, clean out dead code, et cetera
 *
 * Revision 1.15  1996/05/15  22:32:59  jimz
 * remove cache and vs stuff

 * added the interleaved declustering architecture
 * ('I'), with distributed sparing.
 *
 * Revision 1.12  1995/11/17  16:59:45  amiri
 * don't INCLUDE_CHAINDECLUSTER in the kernel
 * source.
