From a80e1f1c90e1fa9142618754ce18f179896f6d7d Mon Sep 17 00:00:00 2001 From: Tony Hutter Date: Tue, 10 Oct 2023 08:57:48 -0700 Subject: zvol: Temporally disable blk-mq 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.
