[DTrace-devel] [PATCH 2/5] test: nfs: don't require a locking daemon

[Nick Alcock]

On modern (NFSv4) systems, there is no guarantee that statd is running,
and indeed it has probably been explicitly turned off (unless writable
NFSv3 exports exist).  This causes mount-time warnings that trigger test
failures unless we disable locking.

No DTrace NFS tests need locking, so disable it.
