Yan, Zheng 3fd0a5585e Btrfs: Metadata ENOSPC handling for balance ... This patch adds metadata ENOSPC handling for the balance code. It is consisted by following major changes: 1. Avoid COW tree leave in the phrase of merging tree. 2. Handle interaction with snapshot creation. 3. make the backref cache can live across transactions.
