返回类型：void

参数：

类型参数名称
struct perf_event *event
void *data
7833  ifh等于perf_event_addr_filters(event)
7834  vma等于data

7845  raw_spin_lock_irqsave( & lock, flags)
7847  如果perf_addr_filter_vma_adjust(filter, vma, & addr_filter_ranges[count])则restart自加
7851  count自加
7854  如果restart则addr_filters_gen自加
7856  raw_spin_unlock_irqrestore( & lock, flags)
7858  如果restart则perf_event_stop(event, 1)
