Hi Jorge.

I tested nfstest_cache on the lastest kernel,there were some
FAIL in the result.(It failed with all versions of nfs)
Is this the cache's bug? Or i missed some arguments ?

./nfstest_cache --nfsversion=4 -e /nfsroot --server 192.168.227.10 --client 192.168.227.12 >cache4.log
(version 3,4.1,4.2 had the same result).
