Presently the size of /proc/kcore which can be read by 'ls -l' is 0. But it's not the correct value. On x86-64, ls -l shows ... root root 140737486266368 2009-09-17 10:29 /proc/kcore Then, 7FFFFFFE02000. This comes from vmalloc area's size. (*) This shows "core" size, not memory size. This patch shows the size by updating "size" field in struct proc_dir_entry. Later, lookup routine will create inode and fill inode->i_size based on this value. Then, this has a problem. - Once inode is cached, inode->i_size will never be updated. Then, this patch is not memory-hotplug-aware. To update inode->i_size, we have to know dentry or inode. But there is no way to lookup them by inside kernel. Hmmm.... Next patch will try it.
