+ * Log: rf_disks.c,v
+ * Revision 1.32 1996/07/27 18:40:24 jimz
+ * cleanup sweep
+ *
+ * Revision 1.31 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 1.30 1996/07/19 16:11:21 jimz
+ * pass devname to DoReadCapacity
+ *
+ * Revision 1.29 1996/07/18 22:57:14 jimz
+ * port simulator to AIX
+ *
+ * Revision 1.28 1996/07/10 22:28:38 jimz
+ * get rid of obsolete row statuses (dead,degraded2)
+ *
+ * Revision 1.27 1996/06/10 12:06:14 jimz
+ * don't do any SCSI op stuff in simulator at all
+ *
+ * Revision 1.26 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 1.25 1996/06/09 02:36:46 jimz
+ * lots of little crufty cleanup- fixup whitespace
+ * issues, comment #ifdefs, improve typing in some
+ * places (esp size-related)
+ *
+ * Revision 1.24 1996/06/07 21:33:04 jimz
+ * begin using consistent types for sector numbers,
+ * stripe numbers, row+col numbers, recon unit numbers
+ *
+ * Revision 1.23 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 1.22 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 1.21 1996/05/30 23:22:16 jimz
+ * bugfixes of serialization, timing problems
+ * more cleanup
+ *
+ * Revision 1.20 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 1.19 1996/05/27 18:56:37 jimz
+ * more code cleanup
+ * better typing
+ * compiles in all 3 environments
+ *
+ * Revision 1.18 1996/05/24 22:17:04 jimz
+ * continue code + namespace cleanup
+ * typed a bunch of flags
+ *
+ * Revision 1.17 1996/05/24 01:59:45 jimz
+ * another checkpoint in code cleanup for release
+ * time to sync kernel tree
+ *
+ * Revision 1.16 1996/05/23 21:46:35 jimz
+ * checkpoint in code cleanup (release prep)
+ * lots of types, function names have been fixed
+ *
+ * Revision 1.15 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 1.14 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 1.13 1996/05/02 14:57:43 jimz
+ * initialize sectorMask
+ *
+ * Revision 1.12 1995/12/01 15:57:04 root
