Subject: [PATCHSET 0/8] perf sched: Fix various memory leaks

Hello,

While running the new perf sched test with ASAN, it fails due to
memory leaks.  They comes mostly from missing thread__put() but
sometimes it needs to release other data structures.

Fix those leaks and add more subcommands to the test.

Thanks,
Namhyung
