+/* 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.
+ *
+ * :  
+ * Log: rf_archs.h,v 
+ * Revision 1.32  1996/08/20 23:05:40  jimz
+ * define RF_KEEP_DISKSTATS to 1

+ *
+ * Revision 1.30  1996/07/27  23:36:08  jimz
+ * Solaris port of simulator
+ *
+ * Revision 1.29  1996/07/26  20:11:46  jimz
+ * only define RF_DEMO for CMU_PDL
+ *
+ * Revision 1.28  1996/07/26  20:10:57  jimz
+ * define RF_CMU_PDL only if it isn't already defined
+ *
+ * Revision 1.27  1996/07/18  22:57:14  jimz
+ * port simulator to AIX
+ *
+ * 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
+ * turn on RF_CMU_PDL by default
+ *
+ * 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
+ * added symbols for enabling forward or backward error
+ * recovery experiments
+ *
+ * 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
+ *
+ * Revision 1.14  1995/11/30  16:27:34  wvcii
+ * added copyright info
+ *
+ * Revision 1.13  1995/11/28  21:23:44  amiri
+ * 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.
+ *
+ * Revision 1.11  1995/11/16  16:15:21  amiri
+ * don't include RAID5 with rotated sparing (INCLUDE_RAID5_RS) in kernel
+ *
+ * Revision 1.10  1995/10/12  17:40:47  jimz

+ * don't INCLUDE_VS
+ *
+ * Revision 1.7  1995/10/04  03:51:20  wvcii
+ * added raid 1
