David Chinner f9114eba1e [XFS] Prevent lockdep false positives when locking two inodes. ... If we call xfs_lock_two_inodes() to grab both the iolock and the ilock, then drop the ilocks on both inodes, then grab them again (as xfs_swap_extents() does) then lockdep will report a locking order problem. This is a false positive. To avoid this, disallow xfs_lock_two_inodes() fom locking both inode locks at once - force calers to make two separate calls. This means that nested dropping and regaining of the ilocks will retain the same lockdep subclass and so lockdep will not see anything wrong with this code.
