+	* CFS:
+	- Optimize away all directories in cfs_permission() since a recheck occurs after getting token.
+	- Regression:
+	  - skipping cfs_permission() entirely.
+
+	* IPC:
+	- Fix [ ssic-linux-Bugs-2719607 ] memory leak in ipcname_gettotal() path; based on patch from John Hughes (hughesj).
+	  - sizing & allocation of struct ssi_nodeid_pair array now ipcname_gettotal() callers' responsibility.
+	  - now RPC encodes/decodes struct ssi_nodeid_pair array as a vector and not a buffer.
