    md: load/store badblock list from v1.x metadata · 2699b672
    NeilBrown authored
    Space must have been allocated when array was created.
    A feature flag is set when the badblock list is non-empty, to
    ensure old kernels don't load and trust the whole device.
    
    We only update the on-disk badblocklist when it has changed.
    If the badblocklist (or other metadata) is stored on a bad block, we
    don't cope very well.
    
    If metadata has no room for bad block, flag bad-blocks as disabled,
    and do the same for 0.90 metadata.
