Maybe calling disk_set_zoned() before blk_mq_unfreeze_queue() should be enough ?
rescan/revalidate will be done in case you get a topology change event (or
equivalent), which I think is not the case here.

Hi Damien,

I will look into calling disk_set_zoned() before blk_mq_unfreeze_queue().

Thanks,

Bart.
