* 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

|
* 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 1.18 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
|

|
* 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.

|
* changed all instances of mutex_t and cond_t to DECLARE macros
|
|
* converted configuration code to use config structure
|
|
*
