I kept getting warnings from evict because we were calling btrfs_start_transaction() with a transaction already started when doing a balance. This is because we remove a block group which requires a transaction, and the put the last reference on the cache inode. Instead of doing this we need to delay the iput so it is done not within a transaction having started. This gets rid of our warnings. Thanks,
