NFSv4: Implement the fs_locations function call
NFSv4 allows for the fact that filesystems may be replicated across several servers or that they may be migrated to a backup server in case of failure of the primary server. fs_locations is an NFSv4 operation for retrieving information about the location of migrated and/or replicated filesystems. Based on an initial implementation by Jiaying Zhang <jiayingz@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
