From 203126293cd78c56578e33dfe8d517e7e83941a8 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada <yamada.masahiro@socionext.com> Date: Wed, 16 Oct 2019 14:15:46 +0900 Subject: [PATCH] kbuild: reduce KBUILD_SINGLE_TARGETS as descending into subdirectories KBUILD_SINGLE_TARGETS does not need to contain all the targets. Change it to keep track the targets only from the current directory and its subdirectories.
