+stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2 
+Fix SFU style symlinks and mknod needed for servers which do not support the
+CIFS Unix Extensions.  Fix setfacl/getfacl on bigendian. Timeout negative
+dentries so files that the client sees as deleted but that later get created
+on the server will be recognized.  Add client side permission check on setattr.
