Subject: [PATCH] libtraceevent/sched_switch: Do not have sched_switch plugin complain about target_cpu
Date: Thu, 9 Sep 2021 16:06:56 -0400 [thread overview]
Message-ID: <20210909160656.21f27793@gandalf.local.home> (raw)
From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>
Older kernels did not have "target_cpu" as a field for wake up events. Do
not complain if it doesn't exist.
Fixes: 159f118588 ("libtraceevent: Do not print message if wakeup success field is missing")
Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
