The following is a series of patches related to Unionfs. Aside from a few
minor cleanups/fixes, the two main changes are (1) lower nameidata support
so we can stack on nfsv4, and (2) un/likely optimizations. These patches
were tested (where appropriate) on our 2.6.23-rc8 latest code, as well as
the backports to 2.6.{22,21,20,19,18,9} on ext2/3/4, xfs, reiserfs,
nfs2/3/4, jffs2, ramfs, tmpfs, cramfs, and squashfs (where available). See
http://unionfs.filesystems.org/ to download backported unionfs code.
