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

Hi all,

After merging the device-mapper tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/md/dm-thin.c: In function '__pool_destroy':
drivers/md/dm-thin.c:2780:2: error: implicit declaration of function 'vfree' [-Werror=implicit-function-declaration]
  vfree(pool->cell_sort_array);
  ^
drivers/md/dm-thin.c: In function 'pool_create':
drivers/md/dm-thin.c:2893:2: error: implicit declaration of function 'vmalloc' [-Werror=implicit-function-declaration]
  pool->cell_sort_array = vmalloc(sizeof(*pool->cell_sort_array) * CELL_SORT_ARRAY_SIZE);
  ^
drivers/md/dm-thin.c:2893:24: warning: assignment makes pointer from integer without a cast
  pool->cell_sort_array = vmalloc(sizeof(*pool->cell_sort_array) * CELL_SORT_ARRAY_SIZE);
                        ^

Caused by commit

  94212d3b6054 ("dm thin: allocate the cell_sort_array dynamically")

Forgot to include vmalloc.h

I have used the device-mapper from next-20150703 for today.
