    block: kill swap_io_context() · 3bc217ff
    Jens Axboe authored
    It blindly copies everything in the io_context, including the lock.
    That doesn't work so well for either lock ordering or lockdep.
    
    There seems zero point in swapping io contexts on a request to request
    merge, so the best point of action is to just remove it.
