Hi Andrew, After merging the akpm tree, today's linux-next build (x86_64 allmodconfig) failed like this: fs/f2fs/node.c: In function 'init_free_nid_cache': fs/f2fs/node.c:2634:25: error: implicit declaration of function 'f2fs_kvzalloc' [-Werror=implicit-function-declaration] nm_i->free_nid_count = f2fs_kvzalloc(nm_i->nat_blocks * ^ fs/f2fs/node.c:2634:23: warning: assignment makes pointer from integer without a cast [-Wint-conversion] nm_i->free_nid_count = f2fs_kvzalloc(nm_i->nat_blocks * ^ Caused by commit 69e5e80117a3 ("mm: introduce kv[mz]alloc helpers") interacting with commit c48b15867a2f ("f2fs: skip scanning free nid bitmap of full NAT blocks") from the f2fs tree.
