From: Ankur Arora <hidden>
Date: 2026-08-31 20:23:54
Also in:
bpf, linux-arch, linux-pm, lkml
Subsystem:
arm architected timer driver, arm64 port (aarch64 architecture), clocksource, clockevent drivers, the rest · Maintainers:
Mark Rutland, Marc Zyngier, Catalin Marinas, Will Deacon, Daniel Lezcano, Thomas Gleixner, Linus Torvalds
This enables the barrier tests to be built as a module.
