Subject: [for-next][PATCH 06/12] trace/osnoise: Add migrate-disabled field to the osnoise header
Date: Tue, 26 Oct 2021 12:23:21 -0400 [thread overview]
Message-ID: <20211026162348.446188876@goodmis.org> (raw)
In-Reply-To: 20211026162315.297389528@goodmis.org
From: Daniel Bristot de Oliveira <bristot@kernel.org>
Since "54357f0c9149 tracing: Add migrate-disabled counter to tracing
output," the migrate disabled field is also printed in the !PREEMPR_RT
kernel config. While this information was added to the vast majority of
tracers, osnoise and timerlat were not updated (because they are new
tracers).
Fix osnoise header by adding the information about migrate disabled.
