Johannes Thumshirn 0a05fafe9d btrfs: zoned: introduce a minimal zone size 4M and reject mount ... Zoned devices are expected to have zone sizes in the range of 1-2GB for ZNS SSDs and SMR HDDs have zone sizes of 256MB, so there is no need to allow arbitrarily small zone sizes on btrfs. But for testing purposes with emulated devices it is sometimes desirable to create devices with as small as 4MB zone size to uncover errors. So use 4MB as the smallest possible zone size and reject mounts of devices with a smaller zone size.
