This version is still correct and looks better than the first version, but
I'd still like you to improve some details:
- read some other changelogs and follow the common style. In particular,
in the subject line say /what/ you do ("e.g. use ktime_get instead of
do_gettimeofday", or "avoid using struct timespec") instead of /why/,
but then explain in the changelog text what is wrong with the current
version and why it gets changed like this.
- Below the '---', add a short list of things you have changed since
the previous versions. This part will not get copied into the git
history.

A tiny style comment here: please use ktime_to_ns() to extract the
nanoseconds out of the ktime_t type rather than accessing the tv64
member directly.
