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?
