Hi Andrew,
After merging the akpm tree, today's linux-next build (arm defconfig)
produced this warning:
mm/page_alloc.c:4477:23: warning: 'sanitize_zone_movable_limit' defined but not used [-Wunused-function]
Introduced by commit "page_alloc: introduce zone_movable_limit[] to keep
movable limit for nodes" from the akpm tree. It is defined both when
CONFIG_HAVE_MEMBLOCK_NODE_MAP is defined and not, but only used if it is
defined.
Hi Stephen,
Thank you for reporting this. :)
I was aware of this problem by the kbuild rebot, and I think this
problem has been fixed
by the following patch I sent yesterday, and merged into -mm tree this
morning.
Since I could access the lkml web site today, I cannot get an url for you.
Please tell me if your problem is not solved after applying this patch. :)
Thanks. :)
[PATCH Bug fix 3/4] Bug fix: Remove the unused
sanitize_zone_movable_limit() definition.
When CONFIG_HAVE_MEMBLOCK_NODE_MAP is not defined,
sanitize_zone_movable_limit()
is also not used. So remove it.
