We can traverse all inodes now by walking the per-AG inode radix trees without needing a separate list. This enables us to remove a bunch of complex list traversal code and remove another two pointers from the xfs_inode. Also, by replacing the sync traversal with an ascending inode number traversal, we will issue better inode I/O patterns for writeback triggered by xfssyncd or unmount. Before we make this change, move all the relevant sync code into it's own file in the linux-2.6/ directory. This aggregates VFS specific sync interfacing in the one file and will allow all the subsequent change history to be associated with this file so it is easy to find in future.
