Implement i_op->link(). As aufs supports 'pseudo-link', aufs_link() can make it without copying-up. In the case of aufs_link() has to copy-up, the name of the target file is used as-is, and it is pseudo-linked. In other words, calling link(2) after the copy-up is unnecessary.

Implement i_op->rename(). This is a big monster and I don't like it. In order to call d_move() in aufs lock section, FS_RENAME_DOES_D_MOVE is set to fstype.f_flags. Signed-off-by: J. R. Okajima <hooanon05g@gmail.com>

Here are entry adding inode operations, i_op->create(), symlink(), mkdir(), mknod(), and tmpfile(). Obviously they return EOPNOTSUPP when the target branch fs doesn't support the operation. Signed-off-by: J. R. Okajima <hooanon05g@gmail.com>

As a part of branch-management, aufs maintains all cached inodes, dentries, and opened files in remounting. This commits handles the cached dentries by calling the VFS internal function d_walk(). Signed-off-by: J. R. Okajima <hooanon05g@gmail.com>

The marker to represent that the directory is opaque (stop digging down the branch stack) is implemented as a special whiteout. See also the document in previous commit. Signed-off-by: J. R. Okajima <hooanon05g@gmail.com>

The whiteout represents a logical deletion. Although the document in this commit mentioned about rmdir(2) and rename(2) for dir, this commit doesn't contain such functions. They will be added in later commits. Signed-off-by: J. R. Okajima <hooanon05g@gmail.com>

The generation of iinfo and dinfo inherit sbinfo's. Also iinfo generation tracks the branch inode's generation to test the matching after the branch management. Signed-off-by: J. R. Okajima <hooanon05g@gmail.com>

The structure is very similar to aufs inode info (in previous commit). Signed-off-by: J. R. Okajima <hooanon05g@gmail.com>
