From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
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("..").
Trond Myklebust (2):
NFSv3: Refactor nfs3_proc_lookup() to split out the dentry
NFSv3: Add emulation of the lookupp() operation
