As the comment block in include/trace/define_trace.h says, TRACE_INCLUDE_PATH should be a relative path to the define_trace.h ../../drivers/lightnvm is the correct relative path. ../../../drivers/lightnvm is working by coincidence because the top Makefile adds -I$(srctree)/arch/$(SRCARCH)/include as a header search path, but we should not rely on it.
