Subject: [PATCH v8 05/12] kselftest: arm64: extend test_init functionalities
Date: Wed, 9 Oct 2019 09:26:04 +0100 [thread overview]
Message-ID: <20191009082611.9441-6-cristian.marussi@arm.com> (raw)
In-Reply-To: <20191009082611.9441-1-cristian.marussi@arm.com>
Extend signal testing framework to allow the definition of a custom per
test initialization function to be run at the end of the common test_init
after test setup phase has completed and before test-run routine.
This custom per-test initialization function also enables the test writer
to decide on its own when forcibly skip the test itself using standard KSFT
mechanism.
Signed-off-by: Cristian Marussi <cristian.marussi@arm.com>

v7 --> v8
- per test .init() helper added new in v8 (splitted out of v7 05/11)
