Test a particular scenario where we fsync a directory, then move one of its children directories into another directory and then finally sync the log trees by fsyncing any other inode. We want to check that after a power failure we are able to mount the filesystem and that the moved directory exists only as a child of the directory we moved it into. This currently fails on a 5.12 kernel (and 5.13-rc1) but is fixed by a patch with the following subject: "btrfs: fix removed dentries still existing after log is synced" The failure is due to ending up with a directory that has 2 hard links (two parent directories) as soon as the log replay procedure finishes, which causes the tree checker to detect the issue and cause the mount operation to fail with -EIO.
