 Aufs is a stackable unification filesystem such as Unionfs, which
 unifies several directories and provides a merged single directory.

 Faking nameidata (VFS internal data), you can get better performance
 in some cases.

 Specifies the maximum number of branches (or member directories) in a
 single aufs. The larger value consumes more system resources.

config AUFS_COMPAT
 bool "Compatibility with Unionfs (obsolete)"
 default n
 help
 This makes aufs compatible with unionfs-style mount options and some
 behaviours.
 The dirs= mount option and =nfsro branch permission flag are always
 interpreted as br: mount option and =ro flag respectively. The
 'debug', 'delete' and 'imap' mount options are ignored.
 If you disable this option, you will get,
 - aufs issues a wanring about the ignored mount options
 - the default branch permission flag is set. RW for the first branch,
   and RO for the rests.
 - the name of a internal file which represents the directory is
   'opaque', becomes '.wh..wh..opq'
 - the 'diropq=w' mount option is set by default
