"Linus Torvalds' Tab Injection Fix for Kconfig Parsers"
Originally Published 1 year ago — by Phoronix
Linus Torvalds has added intentional hidden tabs to the common Kconfig file for handling page sizes in the Linux kernel to thwart Kconfig parsers that can't correctly handle them, following a patch that replaced a tab with a space character. Torvalds authored the patch to intentionally add tabs to throw off any out-of-tree/third-party parsers that can't correctly handle them, emphasizing that if a parser can't handle tabs as whitespace, it should not be parsing the kernel Kconfig files.
