Filipe Manana edaea8a075 btrfs: regression test for btrfs incremental send
This is a regression test for a btrfs incremental send issue.
If between two snapshots we rename an existing directory named X to Y and
make it a child (direct or not) of a new inode named X, we were delaying
the move/rename of the former directory unnecessarily, which would result
in attempting to rename the new directory from its orphan name to name X
prematurely. This made btrfs receive fail with an error message like the
following:

   rename o261-7-0 -> merlin/RC/OSD failed

This issue was a regression in the 3.16 kernel and got fixed by the
following linux kernel btrfs patch:

   Btrfs: send, don't delay dir move if there's a new parent inode
