[PATCH v10 2/8] rust: time: Add PartialEq/Eq/PartialOrd/Ord trait to Ktime

From: FUJITA Tomonori <fujita.tomonori@gmail.com>
Date: 2025-02-07 13:31:41
Also in: lkml, rust-for-linux
Subsystem: delay, sleep, timekeeping, timers [rust], rust, the rest · Maintainers: Andreas Hindborg, Miguel Ojeda, Linus Torvalds

Add PartialEq/Eq/PartialOrd/Ord trait to Ktime so two Ktime instances
can be compared to determine whether a timeout is met or not.

Use the derive implements; we directly touch C's ktime_t rather than
using the C's accessors because it is more efficient and we already do
in the existing code (Ktime::sub).
