From 622445541b751ce70a952b8486ce4512a792c0a2 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 25 Jul 2019 17:05:13 +0900 Subject: [PATCH] kbuild: detect missing "WITH Linux-syscall-note" for uapi headers UAPI headers licensed under GPL are supposed to have exception "WITH Linux-syscall-note" so that they can be included into non-GPL user space application code. Unfortunately, people often miss to add it. Break 'make headers' when any of exported headers lacks the exception note so that the 0-day bot can easily catch it.
