From: Shraddha Barke <shraddha.6...@gmail.com>
32-bit systems using 'struct timeval' will break in the year 2038,
in order to avoid that the code should be replaced with appropriate
types. This patch replaces timeval with 64-bit ktime_t which is y2038
safe. Here, time64_t is used directly since mlc->lcv_t is interested
only in seconds.
