    Btrfs: Fix a number of inline extent problems that Yan Zheng reported. · 179e29e4

    The fixes do a number of things:
    
    1) Most btrfs_drop_extent callers will try to leave the inline extents in
    place.  It can truncate bytes off the beginning of the inline extent if
    required.
    
    2) writepage can now update the inline extent, allowing mmap writes to
    go directly into the inline extent.
    
    3) btrfs_truncate_in_transaction truncates inline extents
    
    4) extent_map.c fixed to not merge inline extent mappings and hole
    mappings together
