The array of preallocated garbage is to be killed by instantiating the driver-private state at ->open() or at the time of file attachment or whatever (I myself am not entirely sure of the right way to go about it). I think someone's working on writing a patch of that form. I'm not sure what they say is to be done about the gendisk array but I think there are other ways to find the things by major and minor numbers. IOW teaching loop.c to allocate more is not the way to go; one should rather teach it to avoid doing all those allocations up-front. -- wli - 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/
