From 084aa00162bda02bcab501c2b0a0ea9252d291b2 Mon Sep 17 00:00:00 2001 From: Aditya Srivastava Date: Sat, 6 Mar 2021 17:05:10 +0530 Subject: scripts: kernel-doc: fix attribute capture in function parsing Currently, kernel-doc warns for function prototype parsing on the presence of attributes "__attribute_const__" and "__flatten" in the definition. There are 166 occurrences in ~70 files in the kernel tree for "__attribute_const__" and 5 occurrences in 4 files for "__flatten". Out of 166, there are 3 occurrences in three different files with "__attribute_const__" and a preceding kernel-doc; and, 1 occurrence in ./mm/percpu.c for "__flatten" with a preceding kernel-doc. All other occurrences have no preceding kernel-doc. Add support for "__attribute_const__" and "__flatten" attributes. A quick evaluation by running 'kernel-doc -none' on kernel-tree reveals that no additional warning or error has been added or removed by the fix.
