The most significant changes are several fixes to races/locking. This release also supports newer APIs in 2.6.25-rc: not using iget/read_inode, using the changed d_path, using the revised nameidata which embeds a struct path, and using path_get/put. These patches were tested (where appropriate) on 2.6.25, MM, as well as the backports to 2.6.{24,23,22,21,20,19,18,9} on ext2/3/4, xfs, reiserfs, nfs2/3/4, jffs2, ramfs, tmpfs, cramfs, and squashfs (where available). Also tested with LTP-full and with a continuous parallel kernel compile (while forcing cache flushing, manipulating lower branches, etc.). See http://unionfs.filesystems.org/ to download back-ported unionfs code.
