    block: unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe drivers · 9fd097b1
    Tejun Heo authored
    In-kernel disk event polling doesn't matter for legacy/fringe drivers
    and may lead to infinite event loop if ->check_events() implementation
    generates events on level condition instead of edge.
    
    Now that block layer supports suppressing exporting unlisted events,
    simply leaving disk->events cleared allows these drivers to keep the
    internal revalidation behavior intact while avoiding weird
    interactions with userland event handler.
