Trond Myklebust 628adfa218 nfsd: Containerise filecache laundrette 
commit 9542e6a643fc69d528dfb3303f145719c61d3050 upstream.

Ensure that if the filecache laundrette gets stuck, it only affects
the knfsd instances of one container.

The notifier callbacks can be called from various contexts so avoid
using synchonous filesystem operations that might deadlock.
