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. * */ #ifndef _RF__RF_DEBUGMEM_H_ #define _RF__RF_DEBUGMEM_H_ #include "rf_archs.h" #include "rf_alloclist.h" #include "rf_options.h" #ifndef KERNEL #if !defined(__NetBSD__) && !defined(__OpenBSD__) void *malloc(), *calloc();
