[PATCH v3 3/3] zonefs: use zone write granularity as block size

[Martin K. Petersen]

Damien,

> Zoned block devices have different granularity constraints for write
> operations into sequential zones. E.g. ZBC and ZAC devices require
> that writes be aligned to the device physical block size while NVMe
> ZNS devices allow logical block size aligned write operations. To
> correctly handle such difference, use the device zone write
> granularity limit to set the block size of a zonefs volume, thus
> allowing the smallest possible write unit for all zoned device types.
