Isn't it there already?
The patch does:
+++ b/tools/perf/util/dso.h @@ -127,6 +127,7 @@ struct dso { const char *long_name; u16 long_name_len; u16 short_name_len; + void *dwfl; /* DWARF debug info */
---------- What you want, on top of that, at a minimum, we somehow limit the number of simultaneously dwfl_begin()'ed DSOs, right?
