[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [XEN PATCH v2 3/6][RESEND] xen/guest_access: address violations of MISRA rule 20.7
MISRA C Rule 20.7 states: "Expressions resulting from the expansion of macro parameters shall be enclosed in parentheses". Therefore, some macro definitions should gain additional parentheses to ensure that all current and future users will be safe with respect to expansions that can possibly alter the semantics of the passed-in macro parameter. No functional change.
