Hi Linus, Please pull this kselftest fixes update for Linux 6.18-rc6 Fixes event-filter-function.tc tracing test failure caused when a first run to sample events triggers kmem_cache_free which interferes with the rest of the test. Fix this calling sample_events twice to eliminate the kmem_cache_free related noise from the sampling. diff is attached. thanks, -- Shuah ---------------------------------------------------------------- The following changes since commit 920aa3a7705a061cb3004572d8b7932b54463dbf: selftests: cachestat: Fix warning on declaration under label (2025-10-22 09:23:18 -0600) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest tags/linux_kselftest-fixes-6.18-rc6 for you to fetch changes up to dd4adb986a86727ed8f56c48b6d0695f1e211e65: selftests/tracing: Run sample events to clear page cache events (2025-11-10 18:00:07 -0700) ---------------------------------------------------------------- linux_kselftest-fixes-6.18-rc6 Fixes event-filter-function.tc tracing test failure caused when a first run to sample events triggers kmem_cache_free which interferes with the rest of the test.
