+ * Log: rf_interdecluster.h,v 
+ * Revision 1.13  1996/07/29 14:05:12  jimz
+ * fix numPUs/numRUs confusion (everything is now numRUs)
+ * clean up some commenting, return values
+ *
+ * Revision 1.12  1996/07/22  19:52:16  jimz
+ * switched node params to RF_DagParam_t, a union of
+ * a 64-bit int and a void *, for better portability
+ * attempted hpux port, but failed partway through for
+ * lack of a single C compiler capable of compiling all
+ * source files
+ *
+ * Revision 1.11  1996/07/13  00:00:59  jimz
+ * sanitized generalized reconstruction architecture
+ * cleaned up head sep, rbuf problems
+ *
+ * Revision 1.10  1996/06/10  11:55:47  jimz
+ * Straightened out some per-array/not-per-array distinctions, fixed
+ * a couple bugs related to confusion. Added shutdown lists. Removed
+ * layout shutdown function (now subsumed by shutdown lists).
+ *
+ * Revision 1.9  1996/06/07  22:26:27  jimz
+ * type-ify which_ru (RF_ReconUnitNum_t)
+ *
+ * Revision 1.8  1996/06/07  21:33:04  jimz
+ * begin using consistent types for sector numbers,
+ * stripe numbers, row+col numbers, recon unit numbers
+ *
+ * Revision 1.7  1996/06/06  18:41:58  jimz
+ * add RAIDIDagSelect
+ *
+ * Revision 1.6  1996/05/31  22:26:54  jimz
+ * fix a lot of mapping problems, memory allocation problems
+ * found some weird lock issues, fixed 'em
+ * more code cleanup
+ *
+ * Revision 1.5  1996/05/27  18:56:37  jimz
+ * more code cleanup
+ * better typing
+ * compiles in all 3 environments
+ *
+ * Revision 1.4  1996/05/24  01:59:45  jimz
+ * another checkpoint in code cleanup for release
+ * time to sync kernel tree
+ *
+ * Revision 1.3  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 1.2  1995/12/01  19:07:25  root
