3.8.13.12 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Josef Bacik <jbacik@xxxxxxxxxxxx> commit 4871c1588f92c6c13f4713a7009f25f217055807 upstream. btrfs_rename was using the root of the old dir instead of the root of the new dir when checking for a hash collision, so if you tried to move a file into a subvol it would freak out because it would see the file you are trying to move in its current root. This fixes the bug where this would fail btrfs subvol create test1 btrfs subvol create test2 mv test1 test2.
