om samplesMasami Hiramatsu (Google) Since the event-filter-function.tc expects the 'exit_mmap()' directly calls 'kmem_cache_free()', this is vulnerable to code modifications. Choose the target function for the filter test from the sample event data so that it can keep test running correctly even if the caller function name will be changed.

This is also the first test to test plain filtering. The filtering has been tested via the trigger logic, which uses the same code, but there was nothing to test just the event filter, so this test is the first to add such a case.
