From c5967e989f1fe702e75d7405b9251ec7e490d847 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 4 Sep 2018 15:46:20 -0700 Subject: checkpatch: add __ro_after_init to known $Attribute __ro_after_init is a specific __attribute__ that checkpatch does currently not understand. Add it to the known $Attribute types so that code that uses variables declared with __ro_after_init are not thought to be a modifier type. This appears as a defect in checkpatch output of code like: static bool trust_cpu __ro_after_init = IS_ENABLED(CONFIG_RANDOM_TRUST_CPU); [...] if (trust_cpu && arch_init) { where checkpatch reports: ERROR: space prohibited after that '&&' (ctx:WxW) if (trust_cpu && arch_init) { Link: http://lkml.kernel.org/r/0fa8a2cb83ade4c525e18261ecf6cfede3015983.camel@perches.com Signed-off-by: Joe Perches Reported-by: Kees Cook Tested-by: Kees Cook Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- scripts/checkpatch.pl | 1 + 1 file changed, 1 insertion(+) (limited to 'scripts/checkpatch.pl') diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl index b4caee6e269c..161b0224d6ae 100755 --- a/scripts/checkpatch.pl +++ b/scripts/checkpatch.pl @@ -380,6 +380,7 @@ our $Attribute = qr{ __noclone| __deprecated| __read_mostly| + __ro_after_init| __kprobes| $InitAttribute| ____cacheline_aligned| -- cgit v1.2.3
