 +Lookup in a Branch
 +----------------------------------------------------------------------
 +Since aufs has a character of sub-VFS (see Introduction), it operates
-+lookup for branches as VFS does. It may be a heavy work. Generally
-+speaking struct nameidata is a bigger structure and includes many
-+information. But almost all lookup operation in aufs is the simplest
-+case, ie. lookup only an entry directly connected to its parent. Digging
-+down the directory hierarchy is unnecessary.
-+
-+VFS has a function lookup_one_len() for that use, but it is not usable
-+for a branch filesystem which requires struct nameidata. So aufs
-+implements a simple lookup wrapper function. When a branch filesystem
-+allows NULL as nameidata, it calls lookup_one_len(). Otherwise it builds
-+a simplest nameidata and calls lookup_hash().
-+Here aufs applies "a principle in NFSD", ie. if the filesystem supports
-+NFS-export, then it has to support NULL as a nameidata parameter for
