From fbaf242c956aff6a07d9e97eaa3a0a48d947de33 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 20 Jul 2024 16:27:38 +0900 Subject: [PATCH] kbuild: move some helper headers from scripts/kconfig/ to scripts/include/ Move array_size.h, hashtable.h, list.h, list_types.h from scripts/kconfig/ to scripts/include/. These headers will be useful for other host programs. Remove scripts/mod/list.h.
