Subject: [PATCHSET 0/8] perf sched: Fix various memory leaks
Date: Wed, 2 Jul 2025 18:49:34 -0700 [thread overview]
Message-ID: <20250703014942.1369397-1-namhyung@kernel.org> (raw)
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
