Test that if we create a hard link for a file F in some directory A, then move some directory or file B from its parent directory C into directory A, fsync file F, power fail and mount the filesystem, the directory/file B is located only at directory A and both links for file F exist. This test is motivated by an issue found in btrfs which is fixed by the following patch for the linux kernel: Btrfs: fix for incorrect directory entries after fsync log replay Tested against ext3/4, xfs, reiserfs and f2fs.
