Jiri Olsa 7b4b82bced perf tools: Show event fd in debug output 
It is useful for debug to see file descriptors for each event.

Before:

  $ perf stat -vvv -e cycles,cache-misses ls
  ...
  sys_perf_event_open: pid 12146  cpu -1  group_fd -1  flags 0x8
  ...
  sys_perf_event_open: pid 12146  cpu -1  group_fd 3  flags 0x8
  sys_perf_event_open failed, error -13

Now:

  $ perf stat -vvv -e cycles,cache-misses ls
  ...
  sys_perf_event_open: pid 12858  cpu -1  group_fd -1  flags 0x8 = 3
  ...
  sys_perf_event_open: pid 12858  cpu -1  group_fd 3  flags 0x8
  sys_perf_event_open failed, error -13
