Merge tag 'linux_kselftest-fixes-6.18-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull kselftest fix from Shuah Khan:
"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 by calling sample_events twice to eliminate the
kmem_cache_free related noise from the sampling"
