+ * rf_debugMem.h -- memory leak debugging module
+ *
+ * IMPORTANT:  if you put the lock/unlock mutex stuff back in here, you
+ *             need to take it out of the routines in debugMem.c
+ *
+ * Log: rf_debugMem.h,v 
+ * Revision 1.27  1996/07/18 22:57:14  jimz
+ * port simulator to AIX
+ *
+ * Revision 1.26  1996/06/11  13:46:43  jimz
+ * make bracing consistent around memory allocation macros
+ *
+ * Revision 1.25  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 1.24  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 1.23  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 1.22  1996/05/27  18:56:37  jimz
+ * more code cleanup
+ * better typing
+ * compiles in all 3 environments
+ *
+ * Revision 1.21  1996/05/23  22:17:40  jimz
+ * fix alloclist macro names for kernel
+ *
+ * Revision 1.20  1996/05/23  21:46:35  jimz
+ * checkpoint in code cleanup (release prep)
+ * lots of types, function names have been fixed
+ *
+ * Revision 1.19  1996/05/23  13:18:23  jimz
+ * include rf_options.h
+ *
+ * Revision 1.18  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 1.17  1996/05/21  18:51:54  jimz
+ * cleaned up macro args
+ *
+ * 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  1996/05/01  16:26:22  jimz
+ * get rid of old ccmn stuff
+ *
+ * Revision 1.14  1995/12/01  15:58:09  root
+ * added copyright info
+ *
+ * Revision 1.13  1995/10/11  15:26:03  jimz
+ * zero memory after allocation in kernel (hide effects
+ * of uninitialized structs)
+ *
+ * Revision 1.12  1995/10/06  17:04:15  jimz
+ * make Malloc and Free in kernel use kernel malloc package, not cam
+ * dbufs (which is gross, and was exhausting cam zalloc limit)
+ *
+ * Revision 1.11  1995/05/01  13:28:00  holland
+ * parity range locks, locking disk requests, recon+parityscan in kernel, etc.
+ *
+ * Revision 1.10  1995/04/24  13:25:51  holland
+ * rewrite to move disk queues, recon, & atomic RMW to kernel
+ *
+ * Revision 1.9  1995/02/17  19:39:56  holland
+ * added size param to all calls to Free().
+ * this is ignored at user level, but necessary in the kernel.
+ *
+ * Revision 1.8  1995/02/10  17:34:10  holland
+ * kernelization changes
+ *
+ * Revision 1.7  1995/02/03  22:31:36  holland
+ * many changes related to kernelization
+ *
+ * Revision 1.6  1995/02/01  15:13:05  holland
+ * moved #include of general.h out of raid.h and into each file
+ *
+ * Revision 1.5  1995/02/01  14:25:19  holland
+ * began changes for kernelization:
+ *      changed all instances of mutex_t and cond_t to DECLARE macros
+ *      converted configuration code to use config structure
+ *
+ * Revision 1.4  1995/01/11  19:27:02  holland
+ * many changes related to performance tuning
+ *
+ * Revision 1.3  1994/11/29  21:34:56  danner
+ * Changed type of redzone_calloc and malloc to void *.
+ *
+ * Revision 1.2  1994/11/28  22:13:23  danner
+ * Many macros converted to functions.
