+
+  random: remove unused tracepoints
+
+  These explicit tracepoints aren't really used and show sign of aging.
+  It's work to keep these up to date, and before I attempted to keep them
+  up to date, they weren't up to date, which indicates that they're not
+  really used. These days there are better ways of introspecting anyway.
