Subject: linux-next: build failure after merge of the akpm tree

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.

I applied the following fix patch:
