+ * Log: rf_driver.h,v
+ * Revision 1.11 1996/07/11 19:08:00 jimz
+ * generalize reconstruction mechanism
+ * allow raid1 reconstructs via copyback (done with array
+ * quiesced, not online, therefore not disk-directed)
+ *
+ * Revision 1.10 1996/06/10 14:18:58 jimz
+ * move user, throughput stats into per-array structure
+ *
+ * Revision 1.9 1996/06/07 21:33:04 jimz
+ * begin using consistent types for sector numbers,
+ * stripe numbers, row+col numbers, recon unit numbers
+ *
+ * Revision 1.8 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 1.7 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 1.6 1996/05/27 18:56:37 jimz
+ * more code cleanup
+ * better typing
+ * compiles in all 3 environments
+ *
+ * Revision 1.5 1996/05/24 22:17:04 jimz
+ * continue code + namespace cleanup
+ * typed a bunch of flags
+ *
+ * Revision 1.4 1996/05/24 04:28:55 jimz
+ * release cleanup ckpt
+ *
+ * Revision 1.3 1996/05/24 01:59:45 jimz
+ * another checkpoint in code cleanup for release
+ * time to sync kernel tree
+ *
+ * Revision 1.2 1996/05/23 21:46:35 jimz
+ * checkpoint in code cleanup (release prep)
+ * lots of types, function names have been fixed
+ *
+ * Revision 1.1 1996/05/18 19:56:10 jimz
+ * Initial revision
