Hi Martin,

In ZBC-2 support has been improved for zones with a size that is not a power
of two by allowing host-managed devices to report gap zones. This patch adds
support for zoned devices for which data zones and gap zones alternate if the
distance between zone start LBAs is a power of two.

Please consider this patch series for kernel v5.19.

Thanks,

Bart.
