Subject: perf tools mem: Fix -t store option for record command

From: Jiri Olsa <[email protected]>

commit 33da54fa86e29b87fe1e83bd0f15b4ef2be53ecb upstream.

Michael reported 'perf mem -t store record' being broken. The reason is latest rework of this area:

commit acbe613e0c03 ("perf tools: Add monitored events array")

We don't mark perf_mem_events store record when -t store option is specified.

Committer notes:

Before:

  # perf mem -t store record usleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.020 MB perf.data (7 samples) ]
  # perf evlist
  cycles:ppp
  #

After:

  # perf mem -t store record usleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.020 MB perf.data (7 samples) ]
  # perf evlist
  cpu/mem-stores/P
