libceph: use timespec64 for r_mtime
The request mtime field is used all over ceph, and is currently represented as a 'timespec' structure in Linux. This changes it to timespec64 to allow times beyond 2038, modifying all users at the same time. [ Remove now redundant ts variable in writepage_nounlock(). ] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Ilya Dryomov <idryomov@gmail.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
