Hi Greg, Arch Linux recently enabled building the kernel documentation in their PKGBUILD, which turned my normally peaceful build into a spamfest of unescaped braces warnings from Perl. These are fixed upstream with the following two patches: 701b3a3c0ac4 ("PATCH scripts/kernel-doc") 673bb2dfc364 ("scripts/kernel-doc: Escape all literal braces in regexes") Could they please be applied to 4.18? They should be clean cherry-picks. Thanks! Nathan
