ubifs: tnc: use monotonic znode timestamp
The tnc uses get_seconds() based timestamps to check the age of a znode, which has two problems: on 32-bit architectures this may overflow in 2038 or 2106, and it gives incorrect information when the system time is updated using settimeofday(). Using montonic timestamps with ktime_get_seconds() solves both thes problems. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Richard Weinberger <richard@nod.at>
