debug_align() was added by commit 84e1c6bb38eb ("x86: Add RO/NX protection for loadable kernel modules") At that time the config item was CONFIG_DEBUG_SET_MODULE_RONX. But nowadays it has changed to CONFIG_STRICT_MODULE_RWX and debug_align() is confusing because it has nothing to do with DEBUG. Rename it strict_align() Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> --- kernel/module/internal.h | 4 ++-- kernel/module/kallsyms.c | 4 ++-- kernel/module/main.c | 14 +++++++------- 3 files changed, 11 insertions(+), 11 deletions(-)
