Subject: [PATCH AUTOSEL 5.4 09/13] selftests/ftrace: Do not trace do_softirq because of PREEMPT_RT
Date: Tue, 22 Feb 2022 21:31:13 -0500 [thread overview]
Message-ID: <20220223023118.241815-9-sashal@kernel.org> (raw)
In-Reply-To: <20220223023118.241815-1-sashal@kernel.org>
From: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>
[ Upstream commit 6fec1ab67f8d60704cc7de64abcfd389ab131542 ]
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.
