Subject: Re: [PATCH 3/5] rust: sync: support using bool with READ_ONCE

Hello,

Can you cite a practical, real-world example of a target where this is the case?
And is this a target that the Linux community has a strong consensus
it should support?
Would it be able to boot with the existing Linux codebase? Could it
then run software?
For example, plug in a USB device and pull images that were written by
another machine?
