Use of DECLARE_COMPLETION_ONSTACK() looks harmful to me because current thread needs to be able to terminate as soon as possible if SIGKILLed (especially when SIGKILLed by OOM killer). If we move something from kmalloc()ed zone to stack, current thread cannot be terminated until that something is guaranteed to no longer be used. I think we need to convert from on-stack objects to kmalloc()ed objects so that current thread acquires ability to terminate as soon as possible. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
