Use BRK to map a range near kernel image, let's call it range X. 2. Calculate how much memory needed to map all the memory, let's say Y Bytes. Use range X to map at least Y Bytes memory near kernel image. 3. Use the mapped memory to map all the rest memory. Does this sound OK to you guys ?oh, no. We just get rid of pre-calculate the buffer size for page tables.
You mean BRK ? I know that and will first use up this memory. Thanks. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ . Don't email: <a href=mailto:"dont@xxxxxxxxx";> email@xxxxxxxxx </a>
