Subject: Re: [RFC PATCH 1/3] arm64: add CPU prefetch and cache modulation sysfs interface
Date: Mon, 24 Aug 2026 17:54:03 +0800	[thread overview]
Message-ID: <20260824095405.3-1-kobak@nvidia.com> (raw)
In-Reply-To: <20260817220750.GB2274565-robh@kernel.org>

Hi Rob,

Thanks for the review.

I will remove the obsolete GPL boilerplate and retain only the SPDX
identifier and copyright notice.

I also understand the broader concern about exposing
implementation-defined controls through a userspace ABI. I will hold v2
until the arm64 maintainers provide direction rather than continuing to
refine an interface they may not accept. If the preferred direction is a
different abstraction—or no userspace interface—I will rework or withdraw
the RFC accordingly.

Thanks,
Koba
