+Subject: [PATCH] [Backport] trace-cmd:Fix buffer overflow in arg_eval
+
+Fix buffer overflow observed when running perf test.
+
+The overflow is when trying to evaluate "1ULL << (64 - 1)" which is
+resulting in -9223372036854775808 which overflows the 20 character
+buffer.
+
+If is possible this bug has been reported before but I still don't see
+any fix checked in:
