From: J. Bruce Fields <[EMAIL PROTECTED]>
Convert NFSv4 to the new lock interface. We don't define any callback for
now, so we're not taking advantage of the asynchronous feature--that's less
critical for the multi-threaded nfsd then it is for the single-threaded
lockd. But this does allow a cluster filesystem to export cluster-coherent
locking to NFS.
