Naohiro Aota 42c0110009 btrfs: zoned: introduce dedicated data write path for zoned filesystems ... If more than one IO is issued for one file extent, these IO can be written to separate regions on a device. Since we cannot map one file extent to such a separate area on a zoned filesystem, we need to follow the "one IO == one ordered extent" rule. The normal buffered, uncompressed and not pre-allocated write path (used by cow_file_range()) sometimes does not follow this rule. It can write a part of an ordered extent when specified a region to write e.g., when its called from fdatasync(). Introduce a dedicated (uncompressed buffered) data write path for zoned filesystems, that will COW the region and write it at once.
