These patches fix a number of issues that Hammerspace has hit when doing
re-exporting of NFS.

- v2: Rebased on top of cel-next.

Jeff Layton (3):
  nfsd: add a new EXPORT_OP_NOWCC flag to struct export_operations
  nfsd: allow filesystems to opt out of subtree checking
  nfsd: close cached files prior to a REMOVE or RENAME that would
    replace target

Trond Myklebust (3):
  exportfs: Add a function to return the raw output from fh_to_dentry()
  nfsd: Fix up nfsd to ensure that timeout errors don't result in ESTALE
  nfsd: Set PF_LOCAL_THROTTLE on local filesystems only
