Why focus exclusively on the desktop, or over-generalize from it to other uses? What is appropriate for them is not necessarily so for the many millions of machines in server rooms and data centers. Also, you present a false dichotomy. "Lose unsaved files for sure" is not the case for many systems, and "not even know" is not necessarily the case. Logging during shutdown is a real thing, as is saving a crash dump for retrieval after reboot. Both have been standard at my last several projects and companies.

As I've said over and over, both approaches - "limp along" and "reboot before causing harm" - need to remain options, for different scenarios. Anyone who treats the one use case they're familiar with as the only one which should drive policy for everyone is doing the community a disservice.

Yes, both need to remain options. Rust-in-kernel needs to be able to support both. That's like half of Linus's ranting there.

The other half is that kernel has a lot of rules of what is safe to be done where, and Rust has to be able to follow those rules, or not be used in those contexts. This is the GFP_ATOMIC part.
