db.db_mtx must be held any time that db.db_data is accessed. All of these functions do have the lock held by a parent; add assertions to ensure that it stays that way. See https://github.com/openzfs/zfs/discussions/17118 * Refactor dbuf_read_bonus to make it obvious why db_rwlock isn't required. * Refactor dbuf_hold_copy to eliminate the db_rwlock Copy data into the newly allocated buffer before assigning it to the db. That way, there will be no need to take db->db_rwlock. * Refactor dbuf_read_hole In the case of an indirect hole, initialize the newly allocated buffer before assigning it to the dmu_buf_impl_t.
