I guess not required for the bug fix but as an idea this type of thing for kmod could be perhaps useful:

Removed #LSP shenanigans from my #nvim config. I don't really care about it and I hate to need external demons to make text editor do its job. It is even worse than plugins, which I neither love. And I never use auto-complete because it does stuff faster than my head can keep up.

Overall for me #ctags is still best possible experience when indexing source code. It crawls deep, does not do anything automatically and does not require external 3rd party prgrams.

And yeah it is stupid as hell, and thus can index whole #Linux tree without trying to understand it. With LSP indexing is build config dependent, which makes it crippled.

With #Rust I use rusty-tags: https://github.com/dan-t/rusty-tags

Good news and this is what I use (before that #vim).

Still, I would take editor any day with zero plugins and best picks of the plugins as additional features :-) And by heart compatibility with the familiar vim commands.

@liw Mä oon aina ollut sitä mieltä, että naiset vois mun puolesta dominoida johtotehtävissä. Aina kun ollut naispomo, niin homma ollut paremmin balanssissa, ja saanut keskittyä ei-toksisessa ympäristössä omaan juttuunsa. Pitäisköhän liittyä, ja tuoda tämä tuon yhdistyksen agendalle!

Kattoo Suomen talouslukujakin niin kyllähän kaikki menny päin helvettiä, kun saatu rinkirunkkausporukka ruoriin.

Kyllähän eka CEO:kin oli nainen, kun aattelee antiikin kreikkaa. Miehet vaan toimitti tyhjää ja juopotteli :-)

@vbabka lol going there has been like a "dark secret" for me, feels like i was doing something nasty :D but tech is tech for me and i'm interested on everything in tech, even blockchains (as a tech, not a vehicle to make profit), so i don't see anything wrong in it.

you can be critical about stuff (like i'm a bit critical on some aspects of rust) without overlooking into it.

@vbabka Yeah, exactly :D Feels like going to a war zone. But they pay the trip, I have a small demo and my old friend Sonja lives Prague so I don't have to brainwash myself for the whole weekend.

@vbabka Yeah, I mean that instruction is a bit ambiguous on the key type :-) I'll just try it for fun and non-profit...

Actually even TCG_TPM is not in x86 defconfig but this would mean two switches just to get the basic environment ongoing if it was not default I think this sweet spot solution in this case.

I think this is quite good middle ways with enabling HMAC by default: https://lkml.org/lkml/2024/5/21/583

I’d like to switch A-subkey from RSA to ECDSA one. Do I just send the public key via email to helpdesk@kernel.org?

@Tutanota My email provider is non-profit organization #Kapsi from Oulu, Finland. It is full shell access (SSH) with 50GB of backed up space and 500GB of dump storage (not backed up). And the servers are within the homeland borders :-) It is essentially a full no compromises account. There's also opt-in services like MySQL (not using tho). The whole package costs me 40 EUR per year. Cannot get over how great it is and has been :-) Oulu is the town where IRC protocol was invented by Jarkko Oikarinen in 1988 and the first IRC server ever turned on.

Took six review rounds to get it but learned something pretty basic about #BuildRoot: pure dependencies should not have Config.ih{.host} at all. In my case the main asset is swtpm, which depends on libtpms. Only swtpm has Config.in.host now and libtpms has only libtpms.{mk,hash}.

Time test packaging Rust program for BuildRoot. Need a full system build for testing a pam module in dev (written in rust).

Any ways to trace more like bpftrace way between core_initcall and before init starts? Like somehow e.g. compiling eBPF blobs to vmlinux or similar.

I use bootconfig and boot-time tracing stuff and it is nice but barely shadow of what you can do with e.g. bpftrace.

I'm actually sort of wondering this #Gitlab CI thing. I mean it is quite easy to run kselftest even today without any patches to mainline kernel. What's the value added?

Made my first post to rust-for-linux list given a pratical need and use. 

I'll make a PoC with asn1rs by simply deleting everything not needed and hammering the rest 🤷 And first in user space and maybe someone with more kernel rust experience can help me out to fit it there.
