Maybe a container number? Anyways the scheme also would reduce the number of lookups needed and thus the general footprint of the VM using sparse. I just looked at the arch code for i386 and x86_64 and it seems that both already have page tables for all of memory. It seems that a virtual memmap like this would just eliminate sparse overhead and not add any additional page table overhead. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
