Yes, newer kernels indeed try to support lockd/statd. In order to use
it, you also need my linux-nfs-*.tar.gz stuff, which includes Jeff
Uphoff's rpc.statd. You can get the file from
in /pub/linux/okir.

Note to glibc2 users: a new version of the user-land nfs stuff is in the
works which will hopefully also compile with glibc.

Using the mount binary from above-mentioned distribution, you can also
turn off NFS locks again by using -o nolock.

I'd be interested to hear both success and failure stories wrt to NFS
file locking. The current implementation is barely tested against
implementations other than my own.
