This makes the nfs client and server code use 'struct inode_time'
instead of 'struct timespec', to lift the time stamp limitation
on 32-bit systems. With NFS version 2 and 3, this means we can
represent years up until 2106 rather than 2038. With NFS version
4, the on-wire representation allows 64-bit seconds.
