There was a report of zvol data loss (#15351) after enabling blk-mq on a zvol backed with 16k physical block sized disks. Out of an abundance of caution, do not allow the user to enable blk-mq until we can look into the issue. Note that blk-mq was not enabled by default on zvols. It was always opt-in via the zvol_use_blk_mq module parameter.
