[GIT PULL] Rust timekeeping for v6.16 From: Andreas Hindborg <a.hindborg@kernel.org>

[Andreas Hindborg <a.hindborg@kernel.org>]

Hi Miguel,

Please pull these changes for Rust timekeeping.

This PR morphs the rust hrtimer subsystem into the rust timekeeping subsystem
covering delay, sleep timekeeping, and timers.

We also add the `Delta` and `Instant` types to replace `Ktime`. We add `Ktime`
locally for `htrimer` while we rework `hrtimer` to use the new types.

In this iteration, `Instant` does not prevent subtracting instants based on
different clock sources. We plan to add this via generics in the next cycle.

The commits were in linux-next since next-20250501.

Rust timekeeping changes for v6.16

 - Morph the rust hrtimer subsystem into the rust timekeeping subsystem,
   covering delay, sleep, timekeeping, timers. This new subsystem has all the
   relevant timekeeping C maintainers listed in the entry.

 - Replace `Ktime` with `Delta` and `Instant` types to represent a duration of
   time and a point in time.

 - Temporarily add `Ktime` to `hrtimer` module to allow `hrtimer` to delay
   converting to `Instant` and `Delta`.
