+There several other patches in aufs3.
+They are all optional. When you meet some problems, they will help you. You
+can find them in the documentation directory.
+
+ - aufs3-loopback.patch
+ Supports a nested loopback mount in a branch-fs. This patch is
+ unnecessary until aufs produces a message such like "you may want to try
+ another patch for loopback file".
+
+ - vfs-ino.patch
+ Modifies a system global kernel internal function get_next_ino() in
+ order to stop assigning 0 for an inode-number. Not directly related to
+ aufs, but recommended generally.
+
+ - tmpfs-idr.patch
+ Keeps the tmpfs inode number as the lowest value. Effective to reduce
+ the size of aufs XINO files for tmpfs branch. Also it prevents the
+ duplication of inode number, which is important for backup
+ tools, aubrsync or other utilities. When you find aufs XINO files for
+ tmpfs branch growing too much, try this patch.
