Mainly a resync.  Maneesh fixed up the sunrpc code to work with dcache_rcu,
so that is back in.

Andrew,

I think dcache_rcu-nfs-server-fix needs to be included irrespective of 
dcache_rcu.  All fs should be using dcache APIs to manipulate dcache hash 
lists.  This is in line with the dcache cleanup patch (dcache_rcu-1) from 
Maneesh that Linus accepted. This seems like a reasonable cleanup. One
change though, we don't need to grab dcache_lock while deleting
dentries from the private list and __d_drop() should suffice here.
Untested replacement patch included.

Thanks
Dipankar
