Except that the (time) range of the list would be limited I don't really see a big difference. Anyway, the biggest cost is the conversion from/to the 64bit ns value and if its main use is sorting, you can use something like this:
typedef union { u64 tv64; struct { #ifdef __BIG_ENDIAN u32 sec, nsec; #else u32 nsec, sec; #endif } tv; } ktimespec;
To compare two time values the tv64 value is sufficient.
