From: John Hubbard <jhubbard@xxxxxxxxxx> Subject: selftests/vm: minor cleanup: Makefile and gup_test.c A few cleanups that don't deserve separate patches, but that also should not clutter up other functional changes: 1. Remove an unnecessary #include <prctl.h> 2. Restore the sorted order of TEST_GEN_FILES. 3. Add -lpthread to the common LDLIBS, as it is harmless and several tests use it. This gets rid of one special rule already.
