From: Filipe Manana <fdmanana@suse.com> Fix a silent failure in case deleting a root reference fails when searching for an item. Then make btrfs_del_root_ref() less likely to run into such type of bug in the future. Details in the changelogs. V2: Fix patch 2/2. If the BTRFS_ROOT_BACKREF_KEY item is not found, but the BTRFS_ROOT_REF_KEY is found, then before we would return -ENOENT and now we were returning 0 (unless an error happened when deleting the BTRFS_ROOT_REF_KEY item). Just return -ENOENT whenever one of the items is not found, all the callers abort the transaction if btrfs_del_root_ref() returns an error.
