In particular, we want to testthat changes to the event propagate to all children, and the SIGTRAPsare in fact synchronously sent to the thread where the event occurred.Note: The "signal_stress" test case is also added later in the series toperf tool's built-in tests. The test here is more elaborate in thatrespect, which on one hand avoids bloating the perf tool unnecessarily,but we also benefit from structured tests with TAP-compliant output thatthe kselftest framework provides.Signed-off-by: Marco Elver <elver@google.com>Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org>Link: https://lkml.kernel.org/r/20210408103605.1676875-8-elver@google.com List of files: /linux-6.15/tools/testing/selftests/perf_events/settings Thu, 08 Apr 2021 10:36:02 +0000 Marco Elver <elver@google.com>
