From: Arnd Bergmann <arnd@xxxxxxxx>
Lustre has 64-bit timestamps in its network data structures, but
on 32 bit systems, it converts them directly into time_t, which is
32 bit wide.
This changes the code to use 64-bit time stamps for files. The Linux
VFS code still uses time_t though, and will be changed in a separate
patch series.
