In order to use the open-by-filehandle functionality with NFSv3, we
need to ensure that the NFS client can convert disconnected dentries
into connected ones by doing a reverse walk of the filesystem path.
To do so, NFSv4 provides the LOOKUPP operation, which does not
exist in NFSv3, but which can usually be emulated using lookup("..").

v2:
 - Fix compilation issues for "NFSv3: Refactor nfs3_proc_lookup() to
   split out the dentry"

Trond Myklebust (2):
  NFSv3: Refactor nfs3_proc_lookup() to split out the dentry
  NFSv3: Add emulation of the lookupp() operation
