Without CONFIG_MIGRATION, we get a build failure when trying to call isolate_movable_page():
mm/memory-failure.c: In function '__soft_offline_page': mm/memory-failure.c:1656:10: error: implicit declaration of function 'isolate_movable_page';did you mean 'isolate_huge_page'? [-Werror=implicit-function-declaration]
This adds one more static inline helper function in the header declaring it. This returns false to indicate that the page was not isolated.
Fixes: mmotm ("HWPOISON: soft offlining for non-lru movable pages") Fixes: bda807d44454 ("mm: migrate: support non-lru movable page migration") Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- include/linux/migrate.h | 3 +++ 1 file changed, 3 insertions(+)
