struct mon_bin_hdr allows for a 64-bit seconds timestamp. The code currently uses 'struct timeval' to populate the timestamp in mon_bin_hdr, which has a 32-bit seconds field and will overflow in year 2038 and beyond. This patch replaces 'struct timeval' with 'struct timespec64' which is y2038 safe. This patch is part of a larger attempt to remove instances of struct timeval and other 32-bit timekeeping (time_t, struct timespec) from the kernel.

As the patch is a week old and Greg hasn't picked it up yet, I'm guessing that he doesn't have it in his queue any more and you should send it once more with my 'Reviewed-by' tag.

This is a very minor comment I still have, and the patch is fine as it, but I tend to prefer ktime_get_real_ts64() over getnstimeofday64() these days. The two functions do the exact same thing, and I hope to remove the latter eventually.
