A longstanding issue with genksyms is that it has hidden syntax errors. For example, genksyms fails to parse the following valid code: int x, __attribute__((__section__(".init.data")))y; Here, only 'y' is annotated by the attribute, although I am not aware of actual uses of this pattern in the kernel tree. When a syntax error occurs, yyerror() is called. However, error_with_pos() is a no-op unless the -w option is provided. You can observe syntax errors by manually passing the -w option. $ echo 'int x, __attribute__((__section__(".init.data")))y;' | scripts/genksyms/genksyms -w <stdin>:1: syntax error This commit allows attributes to be placed between a comma and init_declarator.
