When the underlying filesystems supports NFS export and the "nfs_export"
feature is enabled, an overlay filesystem may be exported to NFS.

+With the "nfs_export" feature, on copy_up of any lower object, an index entry
is created under the index directory. The index entry name is the hexadecimal
representation of the copy up origin file handle. For a non-directory object,
the index entry is a hard link to the upper inode. For a directory object, the
* Find underlying layer by UUID and path type information.
* Decode the underlying filesystem file handle to underlying dentry.
* For a lower file handle, lookup the handle in index directory by name.

+* If a whiteout is found in index, return **ESTALE**. This represents an overlay object that was deleted after its file handle was encoded.
* For a non-directory, instantiate a disconnected overlay dentry from the decoded underlying dentry, the path type and index inode, if found.
* For a directory, use the connected underlying decoded dentry, path type and index, to lookup a connected overlay dentry.
