Oh, oops, sorry about that.
I modified the patch again as below, hope it could be applied this time.

We can enable|disable timer statistics collection (via echo [1|0] >
/proc/timers_stats), this patch adds a 'status' line to display the
current timer collection status. In the meantime I also bump up the
timer stats version to v0.3.
