Subject: [PATCHSET 00/11] perf test: Fix cpu/thread map leaks

Hi,

This patchset fixes memory leaks in the perf test code.  In my company
setup, it runs daily with various sanitizers on, so I want to reduce
the failures due to the leaks not the logic.

This time I've focused on the cpu and thread maps as they are obvious
and easy to fix.  I'll take a look at the rest failures.

I didn't add the Fixes: tags since most changes seem to predate the
libperf change.  I'm not sure if I could just add the original commit
hash as this fix is meaningful only if Asan is enabled..  I'm afraid
the stable tree maintainers will see patches not applied cleanly.  But
I can add them if you want, so please let me know.

It's also available at perf/asan-fix-v1 branch in

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
