-/* :
- * Log: rf_threadid.h,v
- * Revision 1.17 1996/08/12 20:11:17 jimz
- * fix up for AIX4
- *
- * Revision 1.16 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 1.15 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 1.14 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 1.13 1996/05/24 22:17:04 jimz
- * continue code + namespace cleanup
- * typed a bunch of flags
- *
- * Revision 1.12 1996/05/23 21:46:35 jimz
- * checkpoint in code cleanup (release prep)
- * lots of types, function names have been fixed
- *
- * Revision 1.11 1996/05/20 16:13:46 jimz
- * switch to rf_{mutex,cond}_{init,destroy}
- *
- * Revision 1.10 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 1.9 1996/05/17 13:29:06 jimz
- * did a dance on get_threadid such that it will do the pthread_attr_t -> int
- * assignment without warnings, even on really anal compilers
- *
- * Revision 1.8 1995/12/06 15:15:00 root
- * added copyright info
- *
