Subject: mm/page_alloc.c: put is_pageblock_removable_nolock() inside ifdef
is_pageblock_removable_nolock() is not used unless CONFIG_MEMORY_HOTREMOVE
is activated. Move it in between #ifdef sentinel to match prototype in
<linux/memory_hotplug.h>. Silence gcc warning (W=1):
mm/page_alloc.c:7704:6: warning: no previous prototype for `is_pageblock_removable_nolock' [-Wmissing-prototypes]
