+// The following tools viz. exitsnoop, biopattern and bitesize
+// will not work on Android without this libbpf patch:
+//
+// https://lore.kernel.org/bpf/20220523212808.603526-1-connoro@google.com/T/#u
+//
+// The patch is trivial but important as it looks for tracepoints under /sys/kernel/tracing
+// as there is no debugfs on Android.
+//
+// Additionally, any new tools which depend on kernel static tracepoints should
+// have this libbpf patch.
