bug_ebuild/gentoo/sys-fs/aufs4/files

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.
