Test that if we have a file with 2 (or more) hard links in the same parent directory, rename of the hard links, rename one of the other hard links to the old name of the hard link we renamed before, create a new file in the same parent directory with the old name of second hard link we renamed, fsync fsync this new file and power fail, we will be able to mount again the filesystem and the new file and all hard links exist. This test is motivated by a bug found in btrfs, where mounting the filesystem after the power failure resulted in failure with an errno value of EEXIST, which is fixed by a patch for the linux kernel titled: "Btrfs: fix mount failure after fsync due to hard link recreation" Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Eryu Guan <guaneryu@gmail.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
