A freezable kernel thread can enter frozen state during freezing by
either calling try_to_freeze() or using wait_event_freezable() and its
variants. So for the following snippet of code in a kernel thread loop:
wait_event_interruptible_timeout();
try_to_freeze();
We can change it to a simple w

virtblk_revalidate_zones is called unconditionally from
virtblk_config_changed_work from the virtio config_changed callback.
virtblk_revalidate_zones is a bit odd in that it re-clears the zoned
state for host aware or non-zoned devices, which isn't needed unless the
zoned mode changed - but a zone
When zones were first added the SCSI and ATA specs, two different
models were supported (in addition to the drive managed one that
is invisible to the host):
- host managed where non-conventional zones there is strict requirement
to write at the write pointer, or else an error is returned

Hi all,
hen zones were first added the SCSI and ATA specs, two different
models were supported (in addition to the drive managed one that
is invisible to the host):
- host managed where non-conventional zones there is strict requirement
to write at the write pointer, or else an error is retur
disk_clear_zoned only needs to be called when a device reported zone
managed mode first and we clear it. Add a check so that disk_clear_zoned
isn't called on devices that were never zoned.
This avoids a fairly expensive queue freezing when revalidating
conventional devices.

Move reading and checking the zoned model from virtblk_probe_zoned_device
into the caller, leaving only the code to perform the actual setup for
host managed zoned devices in virtblk_probe_zoned_device.
This allows to share the model reading and sharing between builds with
and without CONFIG_BLK_D
Only use disk_set_zoned to actually enable zoned device support.
For clearing it, call disk_clear_zoned, which is renamed from
disk_clear_zone_settings and now directly clears the zoned flag as
well.

This is not the reason for the bug, the reason is:
