    btrfs: add dedicated members for start and length of a block group · b3470b5d
    David Sterba authored Oct 23, 2019
    
    
    The on-disk format of block group item makes use of the key that stores
    the offset and length. This is further used in the code, although this
    makes thing harder to understand. The key is also packed so the
    offset/length is not properly aligned as u64.
    
    Add start (key.objectid) and length (key.offset) members to block group
    and remove the embedded key.  When the item is searched or written, a
    local variable for key is used.
