Sure, no problem. Note that as ktime_get_seconds() uses CLOCK_MONOTONIC, it is
guaranteed to return a number that fits into a positive 32-bit number
(for about 136
years after boot to be precise). Most users of time_after() or
time_after32() are for
jiffies values that do overflow regularly, but it doesn't hurt to use
time_after32()
here for illustration.
