From a9a49c2ad9b9b8ee20668c15ca2b806dbed8ea40 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 30 Mar 2019 21:04:17 +0900 Subject: kbuild: use $(srctree) instead of KBUILD_SRC to check out-of-tree build KBUILD_SRC was conventionally used for some different purposes: [1] To remember the source tree path [2] As a flag to check if sub-make is already done [3] As a flag to check if Kbuild runs out of tree For [1], we do not need to remember it because the top Makefile can compute it by $(realpath $(dir $(lastword $(MAKEFILE_LIST)))) [2] has been replaced with self-commenting 'sub_make_done'. For [3], we can distinguish in-tree/out-of-tree by comparing $(srctree) and '.' This commit converts [3] to prepare for the KBUILD_SRC removal.
