From a40a8a1103051610fdee3d121a50ced09bcc1c54 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 11 Oct 2021 11:06:50 -0700 Subject: scripts: kernel-doc: Ignore __alloc_size() attribute Fixes "Compiler Attributes: add __alloc_size() for better bounds checking" so that the __alloc_size() macro is ignored for function prototypes when generating kerndoc. Avoids warnings like: ./include/linux/slab.h:662: warning: Function parameter or member '1' not described in '__alloc_size' ./include/linux/slab.h:662: warning: Function parameter or member '2' not described in '__alloc_size' ./include/linux/slab.h:662: warning: expecting prototype for kcalloc(). Prototype was for __alloc_size() instead Suggested-by: Matthew Wilcox Reported-by: Stephen Rothwell Signed-off-by: Kees Cook Link: https://lore.kernel.org/r/20211011180650.3603988-1-keescook@chromium.org Signed-off-by: Jonathan Corbet --- scripts/kernel-doc | 1 + 1 file changed, 1 insertion(+) (limited to 'scripts/kernel-doc') diff --git a/scripts/kernel-doc b/scripts/kernel-doc index cfcb60737957..c123bac28f7a 100755 --- a/scripts/kernel-doc +++ b/scripts/kernel-doc @@ -1789,6 +1789,7 @@ sub dump_function($$) { $prototype =~ s/__weak +//; $prototype =~ s/__sched +//; $prototype =~ s/__printf\s*\(\s*\d*\s*,\s*\d*\s*\) +//; + $prototype =~ s/__alloc_size\s*\(\s*\d+\s*(?:,\s*\d+\s*)?\) +//; my $define = $prototype =~ s/^#\s*define\s+//; #ak added $prototype =~ s/__attribute_const__ +//; $prototype =~ s/__attribute__\s*\(\( -- cgit v1.2.3
