[BUG] kmem_cache_create: duplicate cache nfsd4_stateowners

[BUG] kmem_cache_create: duplicate cache nfsd4_stateowners

[Razvan Gavril]

I couldn't get the nfs server running on one of my machine, and by 
looking in dmesg, seams like there is a kernel problem. I use a 
2.6.16.20 vanilla kernel but i remember getting the same error with a 
2.6.17 kernel too, a week ago when trying to run rpc.nfsd. I couldn't 
get any pattern to reproduce it yet but i got it more then once. If you 
need any other info, please contact me.
