Hi Damien Le Moal,
Unfortunately, this commit was reverted due to io hang.
(afd384f0dbea2229fd11159efb86a5b41051c4a9)
You can see the mail thread at the block layer mailing list.
We don't have a solution about io hang yet..
So I have one question.
Is there any possibility of virtblk-driver io hang on zoned devices
without this patch?
Regards,
Suwan Kim
