Subject: [PATCH v1 05/13] perf synthetic-events: Fix uninitialized pthread_join
Date: Mon, 22 Jun 2026 22:35:07 -0700 [thread overview]
Message-ID: <20260623053515.2677888-6-irogers@google.com> (raw)
In-Reply-To: <20260623053515.2677888-1-irogers@google.com>
In perf_event__synthesize_threads(), fix an uninitialized pthread_join()
call when thread creation fails by only joining the successfully
created threads.
Assisted-by: Antigravity:gemini-3.1-pro
Fixes: 340b47f510bb ("perf top: Implement multithreading for perf_event__synthesize_threads")
