3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jeff Mahoney <jeffm@xxxxxxxx> commit 727b9784b6085c99c2f836bf4fcc2848dc9cf904 upstream. Orphans in the fs tree are cleaned up via open_ctree and subvolume orphans are cleaned via btrfs_lookup_dentry -- except when a default subvolume is in use. The name for the default subvolume uses a manual lookup that doesn't trigger orphan cleanup and needs to trigger it manually as well. This doesn't apply to the remount case since the subvolumes are cleaned up by walking the root radix tree.
