Subject: [virtio-dev] [PATCH v2 0/2] virtio-blk: fix a few problems in ZBD-related code
Date: Thu, 30 Mar 2023 17:49:51 -0400 [thread overview]
Message-ID: <20230330214953.1088216-1-dmitry.fomichev@wdc.com> (raw)
This two-part series contains code fixes that are related to the
recently added support for zoned block devices in virtio-blk
driver.
The original ZBD patchset that was merged to the kernel -next was not
the latest and greatest version. The first patch of this series is
essentially a diff between the current code and the final revision of
the original patchset.
The second patch fixes a problem that is observed when a host-managed
zoned device is virtualized via virtio-blk and the driver kernel is
configured without ZBD support (CONFIG_BLK_DEV_ZONED not set). In this
case, the driver must not allow the device scan to succeed in order to
avoid erroneous device operation that may cause data loss. The
second patch adds this currently missing functionality.
v1 -> v2:
- address nits from Damien
- add Review-by tags from Stefan and Damien
