Poll program is a helper to ftracetest, thus make it a generic file and remove it from being run as a test. Currently when executing tests using $ make run_tests CC poll TAP version 13 1..2 # timeout set to 0 # selftests: ftrace: poll # Error: Polling file is not specified not ok 1 selftests: ftrace: poll # exit=255 Fix this by using TEST_GEN_FILES to build the 'poll' binary as a helper rather than as a test.
