From b1aaa546b52baf7cdc97961e9ba445a26948c1af Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 2 Jan 2017 16:22:24 +0100 Subject: kernel-doc: strip attributes even if they have an argument An inline function can have an attribute, as in include/linux/log2.h, and kernel-doc handles this already for simple cases. However, some attributes have arguments (e.g. the "target" attribute). Handle those too. Furthermore, attributes could be at the beginning of a function declaration, before the return type. To correctly handle this case, you need to strip spaces after the attributes; otherwise, dump_function is left confused.
