There are not any major distributions that are still supporting kernels older than 2.6.27 so we can remove many typedefs. The primary motivator for this change is that kernel 5.0 is dropping support for timeval and it would be ideal if the in-kernel time representation can standardize on ktime_t, but 2.6.18 did not support the ktime interface that was needed.
