Subject: linux-next: nfs/ceph tree build failure

Hi all,

Today's linux-next build (x86_64 allmodconfig) failed like this:

fs/ceph/addr.c: In function 'ceph_set_page_dirty':
fs/ceph/addr.c:105: error: 'BDI_RECLAIMABLE' undeclared (first use in this function)

Commit 69f0302c4bd28846c3251e25976a2336cd6a6e6f ("VM: Split out the
accounting of unstable writes from BDI_RECLAIMABLE") from the nfs tree
interacts with commit 1d3576fd10f0d7a104204267b81cf84a07028dad ("ceph:
address space operations") from the ceph tree.

I applied the following patch for today (I am not sure it is correct) and
will keep it as a merge fixup as necessary.
