Zoned block devices reuse the chunk_sectors queue limit to define zone boundaries. If a such a device happens to also report an optimal boundary, do not use that to define the chunk_sectors as that may intermittently interfere with io splitting and zone size queries.

You can safely drop this from stable: nvme zoned devices were only introduced to linux in 5.9.
Dropped, thanks!
