Subject: [PATCH AUTOSEL 5.10 13/18] selftests/ftrace: Do not trace do_softirq because of PREEMPT_RT
Date: Tue, 22 Feb 2022 21:30:30 -0500	[thread overview]
Message-ID: <20220223023035.241551-13-sashal@kernel.org> (raw)
In-Reply-To: <20220223023035.241551-1-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.
