So a maintainer reverts an ABI that he thinks needs more thought/work before it's too late and we're stuck with it forever. Can you please explain what's the problem here? Asking Linus to revert the commit is short-sighted and doesn't solve the problem. Learn to work with the maintainer and save yourself a lot of trouble. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
