Ok, that's fine then. I've removed the WARN_ON() from the patch in my
git tree. This is what I have outstanding for you at
git://git.infradead.org/users/dwmw2/btrfs-kernel-unstable:

Balaji Rao (2):
      Introduce btrfs_iget helper
      NFS support for btrfs - v3

David Woodhouse (7):
      Implement our own copy of the nfsd readdir hack, for older kernels
      Discard sector data in __free_extent()
      Remove special cases for "." and ".."
      Minor cleanup of btrfs_real_readdir()
      Optimise NFS readdir hack slightly; don't call readdir() again when done
      Fill f_fsid field in btrfs_statfs()
      Mask root object ID into f_fsid in btrfs_statfs()
