Correct, and I think we should keep the two changes separate, as the NOP case is trivial. No need to complicate the trivial and common updates (jump_labels and ftrace). But for things like kprobes, we could do a bit more complex code, but it should probably be separate. Perhaps call this text_poke_nop_bp()? -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
