Also if you make the dependency be on helpers.c then you won't get an intermediate helpers.o, and then you don't need to clean it. So the above three lines could just be: $(TEST_GEN_PROGS): helpers.c
I had some trouble getting this to work (hence why I went with the version in the patch), but it looks like this works. I'll include it in the next set.
+EXTRA_CLEAN = helpers.o $(wildcard /tmp/ksft-openat2-*)If you follow my advice above you don't need helpers.o in there. Deleting things from /tmp is also a bit fishy on shared machines, ie. it will error if those files happen to be owned by another user.
Good point. I'll drop that hunk in the next set. Thanks! -- Aleksa Sarai Senior Software Engineer (Containers) SUSE Linux GmbH <https://www.cyphar.com/>
