Hello all, dm_target->len gives me sector count, but I need to know the default sector size discovered by the blk stacking code without assuming 512b. Now that I have the dm .iterate_devices callback defined and my queue_limits are sane by default, how can I get a pointer to the queue_limits structure for my device given a dm_target structure? It looks like I should call dm_get_md_queue() after getting the md from dm_table_get_md(target->table), but dm_get_md_queue is not an exported symbol. Also, is that value correct within the .ctr, or only after the .ctr returns? If after, how can I hook in after limits are assigned but before .map gets called? Otherwise stated, I would like to know the stacked queue_limits corrected for lower layers within the .ctr function.
