Its filename is mm-sparsec-put-clear_hwpoisoned_pages-within-config_memory_hotremove.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Zhang Yanfei <zhangyanfei@xxxxxxxxxxxxxx> Subject: mm/sparse.c: put clear_hwpoisoned_pages within CONFIG_MEMORY_HOTREMOVE With CONFIG_MEMORY_HOTREMOVE unset, there is a compile warning: mm/sparse.c:755: warning: `clear_hwpoisoned_pages' defined but not used And Bisecting it ended up pointing to 4edd7ceff ("mm, hotplug: avoid compiling memory hotremove functions when disabled"). This is because the commit above put sparse_remove_one_section() within the protection of CONFIG_MEMORY_HOTREMOVE but the only user of clear_hwpoisoned_pages() is sparse_remove_one_section(), and it is not within the protection of CONFIG_MEMORY_HOTREMOVE. So put clear_hwpoisoned_pages within CONFIG_MEMORY_HOTREMOVE should fix the warning.
