Phoronix: Linux 6.13 To Drop Fieldbus Just Five Years After Being Merged

Merged back in 2019 was the Fieldbus subsystem as a set of network protocols for real-time distributed control of automated industrial systems. But now five years later, Fieldbus is being removed from the mainline Linux kernel since the code hasn't been maintained...

What would be the alternatives to FieldBus then? It seems nobody ever uses FieldBus at all.

Umm. I don't know what you or said maintainer base that insight on.
Fieldbus and Profibus are like two major players in process control systems.
Fieldbus is also a bit of a misnomer, as that term covers a lot of different protocols.
Anyway. These things do not change a lot. Does not mean they aren't used.

Seems like the Kernel is missing some maintainers, good thing they do all they can to keep every maintainer and not just exclude them because of current politics.

6.12 will maintain support for probably 6 years, and during that time if new users are found they can re-start the work from the code that got removed and re-introduce it. So there should be no problem from removal.

Grow up. Politics and national security have always been a thing and now that the world quite literally runs on code you have to consider both seriously and constantly.

Become intelligent.

Well to consider security it would be much more fruitful to check every commit not just exclude those that look like they belong to an evil state. What if Linus gets paid/forced by Russian secret agencies to implement backdoors? Or is it somehow impossible for non Russians to do evil things?

Don't say "Become intelligent." and follow that up with some bullshit hypothetical scenario.

Wasn't there just a zillion page thread where this topic was discussed ad nauseam?

Bottom line being that working with sanctioned entities can land Linus and his US-resident lieutenants in court or jail. Whether they, you, or I think this is stupid doesn't matter.

I don't work in embedded so I might be talking out of my ass (even more than usual!), but AFAIU this is somewhat industry dependent. E.g. automotive uses CAN bus a lot. There also seems to be a plethora of 'industrial ethernet' standards becoming increasingly popular. Some add just sturdier cabling than the standard optics or twisted pair, but there's also a bunch of stuff for making ethernet usable for real-time and/or safety-critical stuff.
