Some shell tests compete for resources and so can't run with other tests, tag such tests. The "(exclusive)" stems from shared/exclusive to describe how the tests run as if holding a lock. For ARM/coresight tests: Suggested-by: James Clark <james.clark@linaro.org> Additional failing tests: Suggested-by: Namhyung Kim <namhyung@kernel.org> Tested-by: James Clark <james.clark@linaro.org> Signed-off-by: Ian Rogers <irogers@google.com> Cc: Colin Ian King <colin.i.king@gmail.com> Cc: Howard Chu <howardchu95@gmail.com> Cc: Weilin Wang <weilin.wang@intel.com> Cc: Ilya Leoshkevich <iii@linux.ibm.com> Cc: Thomas Richter <tmricht@linux.ibm.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Dapeng Mi <dapeng1.mi@linux.intel.com> Cc: Athira Jajeev <atrajeev@linux.vnet.ibm.com> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Veronika Molnarova <vmolnaro@redhat.com> Link: https://lore.kernel.org/r/20241025192109.132482-6-irogers@google.com Signed-off-by: Namhyung Kim <namhyung@kernel.org>
