Ah, good catch. However, I think this should be moved to EXTRA_CLEAN instead of only removed from TEST_GEN_FILES. (i.e. "pipe" is created by tools/testing/selftests/exec/execveat.c and should be removed.
Hi,
Thank you. tools/testing/selftests/exec/execveat.c creates pipe file and removes it after performing the test on it. I've looked at the code path between creation and deletion of this file. It'll always be removed automatically. So we shouldn't add it to EXTRA_CLEAN.
Thanks, Usama
