 2010/??/??	*** Release of OpenSSI 2.0.0rc1 ***
 
+2011/01/25	rogertsang <[email protected]>
+	* CVS Tags: OPENSSI-FC-1-9-6-PRE69
+
+	* Token Architecture:
+	cluster/ssi/token/tokseq.c
+	- insert_queue: always inline.
+	- tokseq_accept: indicate to compiler unlikely branch direction.
+	- tokseq_accept: access tqentry structure outside critical section.
+	  reduce contention over ts_lock in tokseq structure.
+	- tokseq_accept: reduce stack usage in local scope.
+	- tokseq_accept: immediately process items with seqnum 0 which could be
+	  items created while TSF_DOWN flag was set. we would see these items
+	  if we lost the race with tokseq_cleanup(). fix items stuck in queue.
+
+	* Remote File Block:
+	cluster/ssi/util/rmtfb.c
+	- __rmtfb_getcli_id: add comment before function.
+	- __rmtfb_getcli_id: use newly defined states for rfb_state field in
+	  rmtfb_cli structure.
+	- rmtfb_newcli: use newly defined states for rfb_state field in
+	  rmtfb_cli structure.
+
+	include/cluster/ssi/util/rmtfb.h
+	- define states RFB_READY and RFB_FAIL for rfb_state field in rmtfb_cli
+	  structure.

+	cluster/ssi/cfs/cfs_chard.c
+	- cfs_sb_soft_down: purge caches before calling process_cnodes() to

+	  amount of work during rebuild.

+
+	* Remote File Block:
+	cluster/ssi/util/rmtfb.c (#ifdef RMTFB_HASH_LOCKLESS)
+	- rmtfb_newcli: call rmtfb_remote_tty_ino() and update fields in file
+	  structure outside critical section. reduce rmtfb_newcli_lock
+	  contention.
+
+	* CFS supporting code:
+	fs/inode.c (#ifdef CONFIG_CFS)
+	- process_cnodes: traverse s_inodes list in super_block structure.
+	  avoid traversing other lists that contain inodes from other super
+	  blocks. reduce work.

+	fs/inode.c (#ifdef SHRINK_ICACHE_SB)
+	include/linux/dcache.h (#ifdef SHRINK_ICACHE_SB)

+
+	include/linux/config.h (#ifdef SHRINK_ICACHE_SB)
+	- undefine SHRINK_ICACHE_SB preprocessor macro. no longer used.
