- Linus Torvalds added hidden tabs to Kconfig to challenge parsers that can’t handle them.
- Tabs were intentionally added to the common Kconfig file for page sizes to expose faulty parsers.
- Torvalds believes parsers unable to handle tabs shouldn’t be parsing kernel Kconfig files, aiming to force fixes.
I am more than sure that Linus wrote the original message as he would normally do, and then made it clean and pretty with an AI. Sometimes I resort to this option too.
