We don't need to burn the memory, you can munmap() the unneeded part after allocating it. Just make sure you don't touch it afterwards. We used this method in previous versions, then moved to the current approach which is more aligned with how qemu does things. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
