That moment when old #lkml mails of yourself appear on screen.

""The #Linux rule for regressions is basically based on the philosophical question of "If a tree falls in the forest, and nobody is around to hear it, does it make a sound?".""

Linus wrote that today on #lkml while detesting the whole notion of "ABI changes": https://lore.kernel.org/all/CAHk-%3Dwga8Qu0-OSE9VZbviq9GuqwhPhLUXeAt-S7_9%[email protected]/

To quote more: ""Pretty much any change can be an ABI change - even totally new interfaces change behavior in that something that didn't use to do anything now does something.

[…]

So I absolutely detest the whole notion of "ABI changes". It's a meaningless concept, and I hate it with a passion, because it then results in the "opposite" situation where some projects seem to think that ABI changes are perfectly fine as long as they go along with version number changes.

[…]

So the only thing that matters is if something breaks user-*conscious* behavior.""

And when that happens, the distinction between "bug fix" and "new feature" and "ABI change" matters not one whit, and the change needs to be done differently.

My new favourite Rust hack: you can trick rustfmt into formatting imports with one symbol per line. Found this gem in LKML. It's perfect for large import lists!

#rust #rustfmt #lkml #til

Linus today on #LKML in reply to "A formal request for process clarifications" regarding the non-merge of the TSEM LSM – a Linus Security Module which provides a framework for generic security modeling:

""I already think we have too many of those pointless things. There's a fine line between diversity and "too much confusion because everybody thinks they know best". And the linux security modules passed that line years ago.

So my suggestion is to standardize on normal existing security models instead of thinking that you can do better by making yet another one. Or at least work with the existing people instead of trying to bypass them and ignoring what they tell you.

Yes, I know that security people always think they know best, and they all disagree with each other, which is why we already have tons of security modules. Ask ten people what model is the right one, and you get fifteen different answers.

I'm not in the least interested in becoming some kind of arbiter or voice of sanity in this.
