Subject: [PATCH v1 10/20] perf header: Ensure bitmaps are freed
Date: Tue,  6 Jun 2023 18:43:43 -0700	[thread overview]
Message-ID: <20230607014353.3172466-11-irogers@google.com> (raw)
In-Reply-To: <20230607014353.3172466-1-irogers@google.com>

memory_node bitmaps need a bitmap_free to avoid memory leaks. Caught
by leak sanitizer.
