+# linux-cifs-client dns name resolver helper
+#     called by cifs kernel module upcall to key API to resolve server name 
+#     to IP when module connects to DFS link.  We may eventually make this
+#     C code, but this is a good starting point.
+#     You should have appropriate kernel and keyutils installed.
