    Btrfs: make sure all dirty blocks are written at commit time · 4a8c9a62
    Yan Zheng authored
    Write dirty block groups may allocate new block, and so may add new delayed
    back ref. btrfs_run_delayed_refs may make some block groups dirty.
    
    commit_cowonly_roots does not handle the recursion properly, and some dirty
    blocks can be left unwritten at commit time. This patch moves
    btrfs_run_delayed_refs into the loop that writes dirty block groups, and makes
    the code not break out of the loop until there are no dirty block groups or
    delayed back refs.
