Hi
    I tested an interactive java application.  after a opreport , i found for some functions  L2_CACHE_MISS = REQUESTS_TO_L2 +L2_CACHE_FILL_WRITEBACK +2 . i think there are some problem with my oprofile. How can i deal with this problem!

 the following is the some information after "opcontrol --status":

Event 0: L2_CACHE_MISS:7500:7:1:1
Event 1: REQUESTS_TO_L2:7500:31:1:1
Event 2: L2_CACHE_FILL_WRITEBACK:7500:3:1:1

  and  the oprofiled.log is below:
