Btrfs: more send support for parent/child dir relationship inversion
The commit titled "Btrfs: fix infinite path build loops in incremental send"
didn't cover a particular case where the parent-child relationship inversion
of directories doesn't imply a rename of the new parent directory. This was
due to a simple logic mistake, a logical and instead of a logical or.
Steps to reproduce:
$ mkfs.btrfs -f /dev/sdb3
$ mount /dev/sdb3 /mnt/btrfs
$ mkdir -p /mnt/btrfs/a/b/bar1/bar2/bar3/bar4
$ btrfs subvol snapshot -r /mnt/btrfs /mnt/btrfs/snap1
$ mv /mnt/btrfs/a/b/bar1/bar2/bar3/bar4 /mnt/btrfs/a/b/k44
$ mv /mnt/btrfs/a/b/bar1/bar2/bar3 /mnt/btrfs/a/b/k44
$ mv /mnt/btrfs/a/b/bar1/bar2 /mnt/btrfs/a/b/k44/bar3
$ mv /mnt/btrfs/a/b/bar1 /mnt/btrfs/a/b/k44/bar3/bar2/k11
$ btrfs subvol snapshot -r /mnt/btrfs /mnt/btrfs/snap2
$ btrfs send -p /mnt/btrfs/snap1 /mnt/btrfs/snap2 > /tmp/incremental.send
A patch to update the test btrfs/030 from xfstests, so that it covers
this case, will be submitted soon.
