Subject: [RFC PATCH v4 13/22] tracing: Accept different type for synthetic event fields
Date: Mon, 2 Dec 2019 19:15:43 +0900 [thread overview]
Message-ID: <157528174379.22451.7159526649325076423.stgit@devnote2> (raw)
In-Reply-To: <157528159833.22451.14878731055438721716.stgit@devnote2>
Make the synthetic event accepts a different type field to record.
However, the size and signed flag must be same.
