/* :
* Log: rf_reconbuffer.h,v
* Revision 1.9 1996/07/13 00:00:59 jimz
* sanitized generalized reconstruction architecture
* cleaned up head sep, rbuf problems
*
* 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 1996/06/05 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 1.6 1996/06/03 23:28:26 jimz
* more bugfixes
* check in tree to sync for IPDS runs with current bugfixes
* there still may be a problem with threads in the script test
* getting I/Os stuck- not trivially reproducible (runs ~50 times
* in a row without getting stuck)
*
* Revision 1.5 1996/06/02 17:31:48 jimz
* Moved a lot of global stuff into array structure, where it belongs.
* Fixed up paritylogging, pss modules in this manner. Some general
* code cleanup. Removed lots of dead code, some dead files.
*
* Revision 1.4 1996/05/23 21:46:35 jimz
* checkpoint in code cleanup (release prep)
* lots of types, function names have been fixed
*
* 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 1995/12/06 15:04:47 root
* added copyright info
