- * HISTORY
- * $Log: cfsnc.h,v $
- * Revision 1.2 1998/09/02 19:09:53 rvb
- * Pass2 complete
- *
- * Revision 1.1.1.1 1998/08/29 21:14:52 rvb
- * Very Preliminary Coda
- *
- * Revision 1.8 1998/08/28 18:12:25 rvb
- * Now it also works on FreeBSD -current. This code will be
- * committed to the FreeBSD -current and NetBSD -current
- * trees. It will then be tailored to the particular platform
- * by flushing conditional code.
- *
- * Revision 1.7 1998/08/18 17:05:24 rvb
- * Don't use __RCSID now
- *
- * Revision 1.6 1998/08/18 16:31:49 rvb
- * Sync the code for NetBSD -current; test on 1.3 later
- *
- * Revision 1.5 98/01/23 11:53:51 rvb
- * Bring RVB_CODA1_1 to HEAD
- *
- * Revision 1.4.2.1 97/12/16 12:40:23 rvb
- * Sync with 1.3
- *
- * Revision 1.4 97/12/05 10:39:29 rvb
- * Read CHANGES
- *
- * Revision 1.3.4.3 97/11/24 15:44:51 rvb
- * Final cfs_venus.c w/o macros, but one locking bug
- *
- * Revision 1.3.4.2 97/11/12 12:09:44 rvb
- * reorg pass1
- *
- * Revision 1.3.4.1 97/11/06 21:06:05 rvb
- * don't include headers in headers
- *
- * Revision 1.3 97/08/05 11:08:19 lily
- * Removed cfsnc_replace, replaced it with a coda_find, unhash, and
- * rehash. This fixes a cnode leak and a bug in which the fid is
- * not actually replaced. (cfs_namecache.c, cfsnc.h, cfs_subr.c)
- *
- * Revision 1.2 96/01/02 16:57:19 bnoble
- * Added support for Coda MiniCache and raw inode calls (final commit)
- *
- * Revision 1.1.2.1 1995/12/20 01:57:45 bnoble
- * Added CODA-specific files
- *
- * Revision 3.1.1.1 1995/03/04 19:08:22 bnoble
- * Branch for NetBSD port revisions
- *
- * Revision 3.1 1995/03/04 19:08:21 bnoble
- * Bump to major revision 3 to prepare for NetBSD port
- *
- * Revision 2.2 1994/08/28 19:37:39 luqi
- * Add a new CODA_REPLACE call to allow venus to replace a ViceFid in the
- * mini-cache.
- *
- * In "cfs.h":
- * Add CODA_REPLACE decl.
- *
- * In "cfs_namecache.c":
- * Add routine cfsnc_replace.
- *
- * In "cfs_subr.c":
- * Add case-statement to process CODA_REPLACE.
- *
- * In "cfsnc.h":
- * Add decl for CODA_NC_REPLACE.
- *
- * Revision 2.1 94/07/21 16:25:27 satya
- * Conversion to C++ 3.0; start of Coda Release 2.0
- *
- * Revision 1.2 92/10/27 17:58:34 lily
- * merge kernel/latest and alpha/src/cfs
- *
- * Revision 2.2 90/07/05 11:27:04 mrt
- * Created for the Coda File System.
- * [90/05/23 dcs]
- *
- * Revision 1.4 90/05/31 17:02:12 dcs
- * Prepare for merge with facilities kernel.
