Hi Linus, Please pull the following kselftest fixes update for Linux 6.9-rc5. This kselftest fixes update for Linux 6.9-rc5 consists of a fix to kselftest harness to prevent infinite loop triggered in an assert in FIXTURE_TEARDOWN and a fix to a problem seen in being able to stop subsystem-enable tests when sched events are being traced. diff is attached. thanks, -- Shuah ---------------------------------------------------------------- The following changes since commit 224fe424c356cb5c8f451eca4127f32099a6f764: selftests: dmabuf-heap: add config file for the test (2024-03-29 13:57:14 -0600) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest tags/linux_kselftest-fixes-6.9-rc5 for you to fetch changes up to 72d7cb5c190befbb095bae7737e71560ec0fcaa6: selftests/harness: Prevent infinite loop due to Assert in FIXTURE_TEARDOWN (2024-04-04 10:50:53 -0600) ---------------------------------------------------------------- linux_kselftest-fixes-6.9-rc5 This kselftest fixes update for Linux 6.9-rc5 consists of a fix to kselftest harness to prevent infinite loop triggered in an assert in FIXTURE_TEARDOWN and a fix to a problem seen in being able to stop subsystem-enable tests when sched events are being traced. ---------------------------------------------------------------- Shengyu Li (1): selftests/harness: Prevent infinite loop due to Assert in FIXTURE_TEARDOWN Yuanhe Shu (1): selftests/ftrace: Limit length in subsystem-enable tests tools/testing/selftests/ftrace/test.d/event/subsystem-enable.tc | 6 +++--- tools/testing/selftests/kselftest_harness.h | 5 ++++- 2 files changed, 7 insertions(+), 4 deletions(-) ----------------------------------------------------------------
