+Subject: [PATCH] Make __comps_objmrtree_all() static inline
+
+This helps compilers to scope the symbol correctly
+and apply the inlining optimizations, clang e.g.
+emits the functions and calls in code which is
+suboptimal, therefore give a little help to compiler
+this function is not used anywhere else to have
+a global scope.
