OK, here is the full series so far. I'm resending because I had to fix
up a couple of BDI_UNSTABLE typos in Peter's patch...

Cheers

Peter Zijlstra (1):
      VM: Split out the accounting of unstable writes from BDI_RECLAIMABLE

Trond Myklebust (5):
      NFS: Run COMMIT as an asynchronous RPC call when wbc->for_background is set
      VM: Use per-bdi unstable accounting to improve use of wbc->force_commit
      VM: Don't call bdi_stat(BDI_UNSTABLE) on non-nfs backing-devices
      VM/NFS: The VM must tell the filesystem when to free reclaimable pages
      VFS: Ensure that writeback_single_inode() commits unstable writes
