Sorry, but the existing DM zoned support is only enabled zoned for legacy
devices (e.g. SMR, etc). Those legacy zoned devices aren't a priority for RHEL
(nor RHEL9). It is NVMe with ZNS where "zoned" is meaningful and needed for
RHEL9. But DM needs modification and an entirely new DM target to support
these NVMe ZNS devices(WDC named this target "dm-zap" but has never shared the
code).
So long story short, please drop CONFIG_DM_ZONED change from this MR. I'll
deal with it if/when appropriate. Thanks!
