If you're speaking of the new fs-cache feature of 2.6.30 kernel, and not
of builtin caching of NFS (the one managed by -o noac option), the only
way to disable it AFAIK is to prevent fs-cache module loading in
modutils configuration, using either of:
- blacklist fs-cache
- install fs-cache /bin/true
- alias fs-cache null
