    checkpatch.pl: add union and struct to the exceptions list · 22fd2d3e
    Stefani Seibold 提交于
    Here is a small code snippet, which will be complained about by
    checkpatch.pl:
    
    #define __STRUCT_KFIFO_COMMON(recsize, ptrtype) \
    	union { \
    		struct { \
    			unsigned int	in; \
    			unsigned int	out; \
    		}; \
    		char		rectype[recsize]; \
    		ptrtype		*ptr; \
    		const ptrtype	*ptr_const; \
    	};
    
    This construct is legal and safe, so checkpatch.pl should accept this.  It
    should be also true for struct defined in a macro.
    
    Add the `struct' and `union' keywords to the exceptions list of the
    checkpatch.pl script, to prevent error message "Macros with multiple
    statements should be enclosed in a do - while loop".  Otherwise it is not
    possible to build a struct or union with a macro.
