Subject: [PATCH 3/8] io_uring: include cflags in completion trace event
Date: Fri, 19 Mar 2021 14:35:11 -0600 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
We should be including the completion flags for better introspection on
exactly what completion event was logged.
