* time_after32 - compare two 32-bit relative times
* @a: the time which may be after @b

* time_after32(a, b) returns true if the time @a is after time @b.

* Similar to time_after(), compare two 32-bit timestamps for relative
* times. This is useful for comparing 32-bit seconds values that can't
* be converted to 64-bit values (e.g. due to disk format or wire protocol
* issues) when it is known that the times are less than 68 years apart.
