The current versions of these two macros don't work correctly if the argument expression happens to contain a modulo operator (%) -- when stringified, it gets interpreted as a printf formatting character! With a specifically crafted parameter, this could probably cause a kernel OOPS; consider WARN_ON(p%s) or WARN_ON(f %*pEp). Instead, we should use an explicit "%s" format, with the stringified expression as the coresponding literal-string argument.
