Test that if we have a file F1 with two links, one in a directory A and the other in directory B, if we remove the link in directory B, move some other file F2 from directory B into directory C, fsync inode F1, power fail and remount the filesystem, file F2 exists and is located only in directory C. This is motivated by a bug found in btrfs, which is fixed by the patch (for the linux kernel) titled: "Btrfs: fix file loss on log replay after renaming a file and fsync" Tested against ext3, ext4, xfs, f2fs and reiserfs.
