Subject: [RFC PATCH 1/1] tracing: Use guard() rather than scoped_guard()
Date: Mon, 25 Nov 2024 09:25:14 -0500 [thread overview]
Message-ID: <20241125142514.2897143-1-mathieu.desnoyers@efficios.com> (raw)
Using scoped_guard() in the implementation of trace_##name() adds an
unnecessary level of indentation.
[ This is based on the series "tracing: Remove conditional locking from
tracepoint". ]
