From 6fec1ab67f8d60704cc7de64abcfd389ab131542 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 14 Feb 2022 09:36:57 +0100 Subject: selftests/ftrace: Do not trace do_softirq because of PREEMPT_RT The PREEMPT_RT patchset does not use do_softirq() function thus trying to filter for do_softirq fails for such kernel: echo do_softirq ftracetest: 81: echo: echo: I/O error Choose some other visible function for the test. The function does not have to be actually executed during the test, because it is only testing filter API interface.
