Right now not. We may change that anyway in the future if needed. Steven, how do we proceed with this small series? Since there don't seem to be any objections, I'll repost with the changed notrace define. However I think the whole stuff should go upstream via the ftrace tree. Is that ok with you? FWIW, the s390 gcc hotpatch feature was merged in the meantime: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=11762b8363737591bfb9c66093bc2edf289b917f -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
