I think we can consider such discussions:
(1) I assume that we still need to discuss PO2 zone sizes?
(2) Status of ZNS SSD support in F2FS, btrfs (maybe, bcachefs and other file systems)
(3) Any news from ZoneFS (+ ZenFS maybe)?
(4) New ZNS standard features that we need to support on block layer + FS levels?
(5) ZNS drive emulation + additional testing features?
(6) ZNS + computational drive? What new features would we like to see from ZNS SSD?
(7) ZNS + CXL: does it make sense?

Thanks,
