Subject: [for-next][PATCH 04/16] tracing: Save both wakee and current on wakeup events
Date: Fri, 18 Feb 2022 19:54:34 -0500 [thread overview]
Message-ID: <20220219005512.967943514@goodmis.org> (raw)
In-Reply-To: <20220219005430.848118506@goodmis.org>
From: "Steven Rostedt (Google)" <rostedt@goodmis.org>
Use the sched_switch function to save both the wakee and the waker comms
in the saved cmdlines list when sched_wakeup is done.
