I'm going to also add this patch, to do the same for flags:

diff --git a/event-parse.c b/event-parse.c
index 25e0874..7ef66f8 100644
--- a/event-parse.c
+++ b/event-parse.c
@@ -3950,6 +3950,11 @@ static void print_str_arg(struct trace_seq *s, void *data, int size,
val &= ~fval;
}
}
+ if (val) {
+ if (print && arg->flags.delim)
+ trace_seq_puts(s, arg->flags.delim);
+ trace_seq_printf(s, "0x%llx", val);
+ }
break;
case PRINT_SYMBOL:
val = eval_num_arg(data, size, event, arg->symbol.field);
