From c83b16cefd78f55071840e1159ead9fe62747769 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 7 Jan 2023 18:45:45 +0900 Subject: [PATCH] kbuild: rust: move rust/target.json to scripts/ scripts/ is a better place to generate files used treewide. With target.json moved to scripts/, you do not need to add target.json to no-clean-files or MRPROPER_FILES. 'make clean' does not visit scripts/, but 'make mrproper' does.
