linux-next: build failure after merge of the slab tree

Hi all,

After merging the slab tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/ext4/mballoc.c: In function 'ext4_exit_mballoc':
fs/ext4/mballoc.c:2750: error: implicit declaration of function 'kmem_cache_name'
fs/ext4/mballoc.c:2750: warning: cast to pointer from integer of different size

Caused by commit 63310467a3d1ed6a0460ec1f4268126cd1ceec2e ("mm: Remove
support for kmem_cache_name()").  Clearly the last user has not gone, yet.

I have used the version of the slab tree from next-20110121 for today.
