Subject: [PATCH v6 02/13] perf dso: kernel-doc for enum dso_binary_type
Date: Mon, 17 Mar 2025 20:31:39 -0700	[thread overview]
Message-ID: <20250318033150.119174-3-irogers@google.com> (raw)
In-Reply-To: <20250318033150.119174-1-irogers@google.com>

There are many and non-obvious meanings to the dso_binary_type enum
values. Add kernel-doc to speed interpretting their meanings.
