[PATCH v2] include: linux: Reorganize timekeeping and ktime headers

Carlos Bilbao
2022-02-08T16:11:12Z

The timekeeping subsystem could use some reorganization. Reorganize and
separate the headers by making ktime.h take care of the ktime_get()
family of functions, and reserve timekeeping.h for the actual timekeeping.

This also helps to avoid implicit function errors and strengthens the
header dependencies, since timekeeping.h was using ktime_to_ns(), a static
function defined in a header it does no include, ktime.h.

Include the header timekeeping.h wherever it is necessary for a successful
compilation after the header code reorganization for all archs.
