Actually SECTIONS_SHIFT is used in the kernel code, fixed the code comments. BTW, also moved the code comment to where it's defined. Also fixed a checkpatch complain derived from the original code: WARNING: please, no space before tabs + * SECTIONS_SHIFT ^I^I#bits space required to store a section #$ Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Yu Zhao <redacted> Cc: Andrey Konovalov <andreyknvl@gmail.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Kees Cook <redacted> Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com> --- include/linux/mmzone.h | 2 -- include/linux/page-flags-layout.h | 3 +++ 2 files changed, 3 insertions(+), 2 deletions(-)
