The function dmu_objset_userquota_get_ids() checks and uses dn->dn_bonus outside of dn_struct_rwlock. If the dnode is being freed then the bonus dbuf may be in the process of getting evicted. In this case there is a race that may cause dmu_objset_userquota_get_ids() to access the dbuf after it has been destroyed. To prevent this, ensure that when we are using the bonus dbuf we are either holding a reference on it or have taken dn_struct_rwlock.
