[PATCH v5 0/7] rust/hrtimer: Various hrtimer + time additions

From: Lyude Paul
Date: Fri Jun 13 2025 - 19:28:18 EST


This is a collection of various bindings that I added to hrtimer when I
was originally getting it ready to be used in rvkms. I've mostly been
waiting for Andreas's hrtimer series to go upstream before submitting
these.

All of these are currently being used within rvkms for vblank emulation.

Based on top of Fujita's patch series "rust: time: Convert hrtimer to
use Instant and Delta":
