That seems a reasonable thing to want to do.

Does it need to be this fancy? Why not just have:
if (core_name_format is unset) use "core" else use core_name_format/nodename-uid-pid-comm.core
which saves all that string format processing, while giving people everything they could want? - 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/
