What options are you loading null_blk with?
The issues I reported are the result of running test blk/010 from the blktests suite. That test loads the null_blk kernel module twice: _init_null_blk queue_mode=2 submit_queues=16 nr_devices=32 [ ... ] _exit_null_blk _init_null_blk queue_mode=2 submit_queues=16 nr_devices=32 shared_tags=1 [ ... ] _exit_null_blk Please let me know if you need more information.
