Subject: [PATCH v2 05/13] perf dso: Move dso functions out of dsos
Date: Thu, 21 Mar 2024 09:02:52 -0700 [thread overview]
Message-ID: <20240321160300.1635121-6-irogers@google.com> (raw)
In-Reply-To: <20240321160300.1635121-1-irogers@google.com>
Move dso and dso_id functions to dso.c to match the struct
declarations.
