Hi! I'm wondering how out of tree check is supposed to work for make O=dir run_tests from selftests (or make -C ...) directory? (both with 051f278e9d81 ("kbuild: replace KBUILD_SRCTREE with boolean building_out_of_srctree") and without) make M= ... does not work with run_tests. -- WBR, Yauheni Kaliuta
