I think storing it in the inode is a good solution for the normal case, but we should set aside a bit that says: "extended metadata is too long and stored outside the inode". The inode-area that holds the information normally is then used to point to some external blocks containing it. I think that a similar semantic is implemented for small symlinks in ext2: if the destination path is no longer than a couple of bytes long it is stored directly in the inode, and the symlink takes up 0 blocks (only the inode) Robbe
