Merge patch series "allow file systems to increase the minimum writeback chunk size v2"
Christoph Hellwig <hch@lst.de> says:
The relatively low minimal writeback size of 4MiB leads means that
written back inodes on rotational media are switched a lot. Besides
introducing additional seeks, this also can lead to extreme file
fragmentation on zoned devices when a lot of files are cached relative
to the available writeback bandwidth.
Add a superblock field that allows the file system to override the
default size, and set it to the zone size for zoned XFS.
