The swap extent ioctl passes in a target inode and a temporary inode which are clearly named in the ioctl structure. The code then assigns temp to target and vice versa, making it extremely difficult to work out which inode is which later in the code. Make this consistent throughout the code. Also make xfs_swap_extent static as there are no external users of the function. Signed-off-by: Dave Chinner <david@fromorbit.com> Signed-off-by: Alex Elder <aelder@sgi.com>
