Cmode: perf stats for object with instance system have ops/latency counter values zero

[RKSLEEXAN]

We are observing that the perf stats for system object with instance system has following counter values always zero.

               1."sys_read_latency",
                2. "sys_write_latency",
                3. "read_ops",
                4. "write_ops",

Is this a bug ?
