When zonemode is zbd and block size is not divisor of zone size, write target zone selection does not work as expected. First three patches in this series fix the issue by introducing zone finish operation. First two patches do preparation and the 3rd patch does the fix. This series also fix four more issues related to verify with zonemode zbd. The first issue is that verify is allowed only when block size is divisor of zone size. The 4th patch removes this limitation. The second and third issue are caused by zone reset, which erases data pattern for verify. The 5th and 6th patches adjust verify and zone reset timing to avoid verify errors by the erased data pattern. The last issue is experimental verify, which does not work with zonemode=zbd. The 7th patch checks options to error out when experimental verify is specified together with zonemode=zbd. Four more patches follow to make test cases in t/zbd match with the fixes.
