Together with dropping the references to the se_device from call_rcu context this basically means all pointers in struct se_lun are rcu protected which is much safer if you want to access struct se_lun under rcu protection, as this avoids having to deal with special cases. Additionally that basically allows you to replace lun_sep_lock with rcu_read_lock for anything remotely like a fast path. -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
