Test that an incremental send operation emits the correct path for link and rename operation after swapping the names and locations of several inodes in a way that creates a nasty dependency of rename and link operations. Notably one file has its name and location swapped with a directory for which it used to have a directory entry in it. This test currently fails but a kernel patch for it exists and has the following subject: "btrfs: send, orphanize first all conflicting inodes when processing references" Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
