(My, what long lines you have!) We can't reasonably address this with gcc changes. If gcc starts doing what we want in the next release, how long will it be until that release is the *oldest* version of gcc which the kernel may be compiled with? Five years? -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
