    Btrfs: add a log of past tree roots · af31f5e5
    Chris Mason authored
    This takes some of the free space in the btrfs super block
    to record information about most of the roots in the last four
    commits.
    
    It also adds a -o recovery to use the root history log when
    we're not able to read the tree of tree roots, the extent
    tree root, the device tree root or the csum root.
