Subject: [for-next][PATCH 16/26] tracing: Accept different type for synthetic event fields
Date: Tue, 14 Jan 2020 16:03:32 -0500 [thread overview]
Message-ID: <20200114210338.045226017@goodmis.org> (raw)
In-Reply-To: 20200114210316.450821675@goodmis.org
From: Masami Hiramatsu <mhiramat@kernel.org>
Make the synthetic event accepts a different type field to record.
However, the size and signed flag must be same.
