    null_blk: oops when initializing without lightnvm · a514379b
    Matias Bjørling authored
    If the LightNVM subsystem is not compiled into the kernel, and the
    null_blk device driver requests lightnvm to be initialized. The call to
    nvm_register fails and the null_add_dev function cleans up the
    initialization. However, at this point the null block device has
    already been added to the nullb_list and thus a second cleanup will
    occur when the function has returned, that leads to a double call to
    blk_cleanup_queue.
